As shown in fig. 1 and 2, the invention provides a dam engineering digital modeling optimization method, which comprises the following steps:

Preferably, the reference parameters of the total engineering structure of the S1 dam include:

Preferably, the S1 dam body structure parameters include:

s1-4, setting up parameters of core wall of dam engineering,

wherein the first heavy level: obtaining bottom width B of upstream first inverse filtering data of dam engineering_fls1(m) bottom width B of downstream first inverse filter data of dam engineering_flx1(m) bottom elevation H of upstream first unfiltered data of dam engineering_flsd1(m) bottom elevation H of downstream first inverse filtered data of dam engineering_flxd1(m) slope ratio of upstream first inverse filter data of dam engineering I_fls1The slope ratio I of downstream first inverse filtering data of dam engineering_flx1；

The second heavy level: obtaining bottom width B of upstream second inverse filtering data of dam engineering_fls2(m) bottom width B of downstream second inverse filter data of dam engineering_flx2(m) bottom elevation H of upstream second unfiltered data of dam engineering_flsd2(m) bottom elevation H of downstream second inverse filtered data of dam engineering_flxd2(m) slope ratio of upstream second inverse filter data of dam engineering I_fls2The slope ratio I of downstream second inverse filtering data of dam engineering_flx2；

The third tertiary level: obtaining bottom width B of upstream third inverse filter data of dam engineering_fls3(m) bottom width B of downstream third inverse filter data of dam engineering_flx3(m) bottom elevation H of third upstream unfiltered data of dam engineering_flsd3(m) bottom elevation H of downstream third inverse filtered data of dam engineering_flxd3(m) slope ratio of upstream third inverse filter data of dam engineering I_fls3Slope ratio I of downstream third inverse filter data of dam engineering_flx3；

Remarks 1: the method comprises the following steps that a user does not obtain a bottom elevation value of dam engineering, a system defaults to a parameter value which is the same as that of a core wall, namely, the parameter value can be defaulted;

remarks 2: if some dams are not provided with the reverse filter II or the reverse filter III, the system defaults, and as long as the bottom width input by a user is '0', the slope ratio and other parameters are not input any more as long as the material is not available;

s1-6, obtaining the transition material parameters of the dam engineering,

Remarking: according to the construction principle of the dam project, if the bottom elevation parameter data of the dam project are not obtained by a user, the bottom elevation parameter data are consistent with the core wall data, so that the defect that the working process cannot be continued due to the data loss when corresponding parameter data are obtained can be overcome;

s1-7, obtaining rockfill material parameters of dam engineering,

Remarking: according to the construction principle of the dam engineering, if the bottom elevation parameter data of the dam engineering is not obtained by a user, the bottom elevation parameter data is consistent with the core wall data, so that the defect that the working process cannot be continued due to the data loss when corresponding parameter data are obtained can be overcome;

then obtaining the number N of downstream slope corridors of the dam project_mdAnd the corresponding elevation H of the downstream slope surface of the dam project_md(m) downstream slope corresponding width B of dam engineering_md(m) several streets corresponding to the height and width, N_md0 means no horse-road. The corridors are originally external details, but because of the shape and number of rockfill material involved, the corresponding parameter values are input together in this step.

Remarking: after the berm is arranged, the downstream slope of the rockfill material is a broken slope, and the shape and parameters of the downstream slope of the rockfill material are automatically modified according to the number, elevation and width of the berm;

s1-8, obtaining parameters of upstream and downstream slope protection block stone of dam engineering, namely obtaining the thickness H of upstream slope protection block stone of dam engineering_hpkss(m) thickness H of downstream revetment block stone of dam construction_hpksx(m)；

Remarking: if the user only inputs the upstream slope protection block stone thickness H of the dam project_hpkss(m) or downstream revetment block stone thickness H of dam works_hpksx(m) one parameter, missing the other, indicates that the thickness is the same upstream and downstream.

On the surface of which is applied a correction of the horse's path is included. Therefore, the pavement parameters are input firstly, and then the thickness of the stone of the slope protection block is input.

Preferably, the modeling the curved surface of the dam body boundary in S2 includes:

That is, all the points on the plan that can be read accurately and are related to the dam building are read as the primary control points (in short, the design is that the lines, the points and the connecting lines between the points on the plan are all the control points and are read well). Then, part of points between the first-level control points are manually identified to serve as second-level control points, and the program is encrypted and read between the first-level control points and the second-level control points, so that a model which is relatively accordant with actual engineering can be established.

And when the model body is finally corrected, the primary control points cannot be adjusted, and only the points between the primary control points can be automatically adjusted. This is true regardless of the spot check, since it is impossible for either party to read a number in the middle to spot check by themselves.

The calculation of the engineering quantity in the actual engineering is basically carried out in the same step. The denser the control points, the higher the accuracy, but the excessive workload is large.

Preferably, the S2 modeling the internal structure of the dam includes:

S-C, generating parameter data of the upstream cofferdam of the dam body,

The second layer of inverse filter bottom surface is coupled with the first layer of inverse filter bottom surface, and the lower surface of the second layer of inverse filter bottom surface is coupled with the bottom of the dam boundary model.

Or only one layer is arranged, the upper surface of the layer is directly coupled with the bottom surface of each filling area, and the lower surface of the layer is in buried coupling with the dam boundary model;

the outer boundary of the horizontal reverse filtration is the filling area range of the dam body;

therefore, a choice is made here, where the user inputs 0, which means there is only one layer, to couple directly from top to bottom, and if the user inputs 1, which means there are two layers, modeling is performed as described above. There is a choice of "0, 1" as it is commonly referred to herein.

S-H, generating a parameter model of the clay wrapping layer of the dam body

Typically, the bottom gallery, the bedding concrete and the boundary portions may be covered with clay to form a boundary defense system. Generally expressed in terms of clay layer thickness.

remarks 1: if the user inputs that the clay of the bank slope is 0, the bank slope is not filled with clay. If 1 is input, the bank slope is indicated to be filled with clay, and subsequent input modeling is continued. Commonly referred to as 0, 1 selection.

Remarks 2: if the user only inputs one thickness, the total equal thickness is indicated.

Remarks 3: if the first parameter entered by the user is 0, this indicates that no clay filling is required.

a hexahedron figure model program is designed separately, if the system starts the program to generate a figure model, then coordinates (two points) of the bottom surface (certainly a plane) along the river direction central axis are input, and the figure model is transplanted to deduct the occupied space volume.

The idea has a reference meaning for rapidly modifying the model by the simulation operation later, and the idea is added to the place where the user wants to perform the narrow width first filling, and the space is substantially reserved and not filled, so that the idea can be used for constructing an empty substitution block model. The main parameters are as follows:

respectively and sequentially acquiring the upper-stream replacement material filling height H of the dam body_tdss(m) dam body upstream alternate roof elevation H_tdso(m) upstream replacement material filling width B of dam body_tds(m) dam body upstream edge distance from dam axis B_tdsz(m) upstream side slope value I of dam body upstream substitute material_tdssDam body upstream substitute material downstream side slope value I_tdsxUpstream substitution material left trip side slope value I of dam body_tdszAnd on the main body of the damSide slope value I of right trip of trip substitute material_tdsy，

because the dam body connected with the dam body has more tunnels and galleries, the dam body is still distinguished according to the left bank and the right bank, and functional attributes of the dam body, such as grouting gallery, inspection gallery, construction tunnel and drainage tunnel, are defined and carried;

S-L, other internal inlays

The modeling idea is still that a program is written separately to establish a body model, and then the position parameters are input and transplanted to deduct the space volume of the corresponding filling area occupied by the program.

After the body of the dam is modified, the position of the upper dam traffic entrance is moved along with the body (namely, the position is automatically modified along with the body, otherwise, the upper dam traffic entrance can be selected in mid-air or inserted into the dam body).

Remarking: typically, the end points of the dam traffic access points are (and must be) coupled to the dam boundary model, so that only two parameters are needed for determination.

Remarking: it is possible that the requirements of different elevation sections are different, the system defaults to the same, and if not, the user inputs the elevation sections respectively according to different filling materials, that is, the batch of parameters is related to the elevation. For example:

The dam filling process generally does not allow the height difference between different filling areas to be too large, otherwise, the system automatically warns when the intensity is not matched, and a user can modify the dam filling process and can default to the dam filling process, but records the dam filling process.

The following parameter data are obtained:

Remarks 1: the system presets a set of reference values, which indicate default preset reference values if the user does not enter.

Remarks 2: generally the same up and down stream. The user only enters (or modifies) upstream, meaning as upstream and downstream by default.

S4-5, acquiring climate environment limitation standard parameter data;

setting parameter data of rainfall depth and construction limitation;

rainfall depth has great influence on earth and rockfill dam construction, but the restriction of different depths is different, and some depths can be exploited and cannot be filled, and some depths can not be exploited continuously.

Setting the daily rainfall H of the clay material of the main body of the dam_ntyt: when the local rainfall is larger than the value, the clay material stops filling,

the system flexible program gives the daily rainfall depth all year round according to the local rainfall data, and the system is automatically stopped and delayed when meeting the limit during simulation calculation.

In order to ensure the continuity of construction and facilitate organization and management, when the day before and after the occurrence of the construction stop is a work stop day, only the situation that the construction can be carried out for one day (called a solitary day for short) exists in the middle, and the system automatically contains the day in a construction limiting day. If 7 months, 15 days and 17 days are the construction limit days, 16 days are also the construction limit days. In particular, in filling construction, the grade cannot guarantee continuous filling of one unit (in terms of one filling width, not in terms of layers, it is regarded as a construction limit day).

Setting parameter data of the snowing depth and construction limitation;

the snowfall depth has great influence on the construction of the earth-rock dam, but the limitation of different depths is different, some depths can be exploited and cannot be filled, and some depths can not be exploited continuously.

Along with engineering development, construction is gradually needed in Qinghai-Tibet plateau areas, and snowfall cannot be conducted, so that the standard needs to be set, and for inland engineering, a user can directly select to have no limitation, and firstly make 0 and 1 selections.

setting high temperature value T for dam body rockfill material construction_dscg: when the local temperature is higher than the value, the rockfill material stops mining,

the system can preset a set of climate control parameters for the user to refer to, and the user can also newly set the climate control parameters.

(3) Local work and rest time limitation

China is vast in breadth, the difference between the east and the west is hours, and the people who have no meal by thunder do so in common speaking, so the time of local breakfast, lunch and dinner needs to be determined. And the transportation is accurate to the hour traffic flow, so the effective operation time is accurate to the hour.

Breakfast time, e.g. 7: 00-8:30, which comprises the traffic time of arriving at the working face after meals and is different from place to place. [ input parameters ]

Thr lunch time, e.g. 12:00-14:00, also includes the transit time to the working surface after meals, which varies from place to place. [ input parameters ]

Tdr evening meal time, such as 18:00-20:00, also contains the traffic time of arriving at the working face after meals, and is different from place to place. [ input parameters ]

The possible working hours per day is 24 hours minus this time, and then scheduled.

Special process operating time limitation

Open cut blasting operation time T_bpyv: for example, the west generally ranges from 11:00 to 18:30, and if the explosion cannot be carried out at the moment of exceeding 18:30, the delay must be delayed to the next day. This is a time parameter, which has been measured 24 hours in full text.

② open cut measuring paying-off time T_ceyx: it is generally only possible to do this during the day, for example Sichuan 8: 00-18: 30

Automatic adjustment of effective construction time

After the scheme is adjusted and optimized, the system should automatically search, find that the construction is carried out on the construction limit day, should carry forward, find that the construction is carried out on the solitary day, also carry forward, find that the construction is carried out in the rest period also correspondingly carry forward.

The user may determine that the weekend may be constructed, and need to determine in the set selection dialog [ input parameter 1: whether the construction is continuous on weekends or not is judged, and the parameters of 2: whether or not to work continuously in rest period

Although the user makes a selection, the system makes statistics on how many weekend shifts the scheme has, and the extra payroll payments over the weekend shifts are also an aspect of the scheme cost comparison.

S4-6, batch processing of dam body macroscopic control parameter data

All dam main body macro control parameters automatically reserve the determined parameters after the system operates once (the latest parameters are reserved later), a user already has a complete set after the system operates once (next time), and the user can default all the parameters or modify the parameters individually.

Preferably, the S4 weather data includes:

and S4-7, inputting the days of the limitation value of each month of the year by the user, and generating and distributing the days to a specific calendar by the system random number generator for simulation calculation. One set of engineering is generated, different generation parameters are selected in different years, multiple sets of engineering cannot be generated (if 5 years are expected to be needed, 5 groups of random numbers are generated), otherwise different schemes cannot be compared.

S4-8, the large limit value comprises a small limit value, and if the daily rainfall reaches 80mm, the rainfall is more than 30 mm.

The limit value agreed by the formula is used for making a table, and the user only needs to directly fill in possible days of each month.

S4-10, modifying the dam body model of the dam body and the dam abutment:

the design excavation foundation surface can not be modified, and only the surface of the earth can be modified.

Remarking: if the layering boundary of the earth and rock highly weathered layer, the weathered layer and the bedrock on the topographic map can be made, accurate statistics can be carried out, and the method can be made by referring to the developed arch dam excavation model method. It is best to do so to meet the design requirements.

Particularly, major geological defects and the like need to be made, for example, a long river dam is adopted, after dam abutment excavation construction, a long time of shutdown is found when a loose body exists on the left bank and a deep crack exists on the right bank, and the design is temporarily carried out for reinforcement design.

(striping and framing: dividing a flat layer into a plurality of strip-shaped areas for filling and construction, wherein after the flat layer construction is finished, the flat layer is leveled up to form a single width).
