Below in conjunction with the accompanying drawings to the three-dimensional charting geotraverse of the present invention(PRB)Data fuse flow, method and key portion
Part function is described in detail.
Fig. 1 is the geotraverse of the present invention(PRB)Process Data fuse generates the process schematic of three-dimensional geological figure.Fig. 2
It is the present invention from field acquisition geotraverse(PRB)—>By depth integrated treatment->Three-dimensional geological route fence diagrams->Ground
Matter figure(Or real material figure, editor's geologic map)Pass through surface model under frame and three-dimensional geological route fence diagrams frame double constraints
The specific implementation process schematic diagram of three-dimensional geological figure of the modeling tool generation with certain depth of method etc..
As shown in Figure 1 and Figure 2, this method mainly includes the following steps that:
Step 11:The step of logical constraint is carried out to geotraverse PRB sections.
Work as geotraverse(PRB)Data acquisition, cross-sectional data acquisition and geological plane maps(Modeling)After preliminary generation, system
According to geological map, geotraverse sectional view, geology measured section figure, logical constraint calculating is carried out to geotraverse section,
Logic modeling is carried out for correct geologic body relationship.
The constraint of PRB mathematical logics is related to 36 elements of three categories, as shown in figure 3, the inspection according to " check item setting " page
Item is looked into, such as occurrence point data check item, segmentation route data check item, geology limit data check item, is selected in each check item
One or more options the PRB mathematical logics are constrained.
Step 12:To geotraverse(PRB)It is modeled with measured section deep.It specifically includes:
Step 121:Original route is generated automatically according to PRB data(Conveniently)Section, and shown in three-dimensional scenic.As Fig. 4,
Shown in Fig. 5.
Step 122:According to research precision, route section is improved in depth direction.As shown in Figure 6, Figure 7.
Step 123:According to comprehensive analysis or deep data, the modeling of geotraverse depth profiled direction is carried out, and dynamic is raw
Into the three-dimensional geological figure for having certain depth.As shown in Figure 8, Figure 9.
Step 13:According to the step of PRB data acquisition geological boundary occurrence, i.e. the occurrence point domain of influence of geology semantic constraint
Method is estimated with geological boundary occurrence.
In geologic survey geological plane maps, geological boundary and limited occurrence point are the masters for establishing three-dimensional geological body Model
Want information source and modeling foundation.Therefore, can be according to limited occurrence point, and consider a variety of space geometries and geology language
The constraint of justice, occurrence that is correct, reasonably estimating out geological boundary, is directly related to the correct of established three-dimensional geological body Model
Property and reasonability.
Existing occurrence estimates algorithm or directly carries out sample using the buffering area of the occurrence of closest point or setting certain distance
This search or the segmentation trend using distance weighted progress occurrence interpolation, less consideration geological boundary, it is more not yet in effect to be included in ground
Matter semantic constraint.Therefore, how to consider geological boundary trend, the implicit geology semanteme for excavating occurrence point, determined
The reasonable domain of influence of limited production shape point, the fine occurrence for estimating out geological boundary are key technology places.
We carry out sample searches or using distance using the occurrence of closest point or the buffering area of setting certain distance
Weighting carries out occurrence interpolation, while considers the segmentation trend of geological boundary, is effectively included in geology semantic constraint.
Step 131:The step of solving the inflection point of every geological boundary, the geological boundary segmentation include blockade line and do not seal
Abutment line.
A, geological boundary is segmented.For a geological boundary, corresponding rule can be used and be segmented.
B, closed area.As shown in Figure 10, the selection of occurrence point and the assignment side that way of search is divided based on quadrant can be used
Method.
As shown in figure 11.Using the occurrence point selection based on buffer zone analysis mode in assignment method, using geology
The rule of occurrence in the direct line taking of boundary line endpoint occurrence from the nearest occurrence point of endpoint.
Step 132:By the Logic relationship analysis of geologic body, the influence that tomography, rock mass separate is considered, to containing occurrence
Naturally continuous stratigraphic boundary carries out occurrence parameter transmission.As shown in figure 12.
Red occurrence carries out occurrence parameter transmission by spatial analysis to the naturally continuous stratigraphic boundary containing occurrence in figure
Occurrence parameter transmission is carried out to the naturally continuous stratigraphic boundary containing occurrence, occurrence parameter is transmitted without crossover fault.
Step 133:To the geological boundary of occurrence parameter has not been obtained, given using interactive mode by geology expert.
For extremely complicated region or by the traversal of 3~5 times, find there is not the geological boundary of occurrence parameter also, adopt
It is given with interactive mode by geology expert.
Step 14:The step of generating three-dimensional geologic structure/tomography screen work figure.
The step of individually being modeled to the tomography in charting region.Emphasis is examined the fault line of segmentation as an entirety
Consider.
A. it is handled using tomography frame D modeling tool.As shown in figure 13.
According to structure outline map, geology frame model is first established, which is used as charting area three-dimensional geological knot on the whole
The frame of structure, then the geological condition fine degree that foundation data source is reflected is from coarse to fine, builds varigrained three-dimensional successively
Geologic structure model, and finally realize constraint adult of the different grain size geologic body in corresponding geology frame.
Boundary line and its occurrence information of record are contacted according to real material figure interrupting layer, by the way of tri patch, from
Dynamic structure tomography frame model.During practical two dimensional drafting, a layer data, which is often divided into several sections, is expressed,
Each section is respectively provided with different occurrence information.Therefore, when building fault plane threedimensional model, the screening of first layer data is needed
With connection processing, the FAULT MODEL of different sections, using " angle smoothing gradual change " method, carries out fault plane during structure
It seamlessly transits.
B. the step of handling is intersected to tomography.
As shown in figure 14.Geological fault is divided into two kinds of buried fault and exposure tomography, each tomography combines given
Tendency, inclination angle and fracture depth information build fault plane.For buried fault, first to build the 4th is thereon coating,
Then it is that the initial position of bottom surface as tomography of coating extends downwardly using the 4th, builds tomography surface model.
In view of fault plane and the topological relation of geologic body and the processing in public face, each tomography is using segmentation structure
Mode is built, and a usual fault line is made of several sections of specific different occurrences information, and tomography tendency variation may be by blocking up
Slow down, it is also possible to which by gradual stifled, generally use angle gradient technology realizes the smoothing processing of fault plane threedimensional model.Meanwhile
For a plurality of tomography in the case of of intersecting, to consider the major-minor relationship of tomography, first build dominant fault, then build auxiliary tomography, auxiliary tomography
It to be built along dominant fault.
The major-minor fault plane of structure should keep being seamlessly connected under three dimensions.
Therefore, before auxiliary tomography is built, first auxiliary tomography is extended, the friendship between auxiliary tomography and dominant fault is obtained
Line, then build the fault plane of auxiliary tomography.
Step 15:Generate three-dimensional geological route(PRB)The step of section fence diagrams.
By above-mentioned steps 14 as a result, being shown in three-dimensional scenic, as shown in figure 15.It amplifies display effect, such as Figure 16 institutes
Show.
Step 16:Geotraverse(PRB)Section combines the step of modeling with geologic map.
Wherein, geologic body composition includes:
The basic ideas of the geology face construction method of traditional less parallel section are:Two are selected on two adjacent sections
Group can correspond to the segmental arc of splicing, and geology face is established by the way of contour tiling, and main process is adjacent from two
Two groups of corresponding hatchings are found on geologic section and carry out splicing structure geology face.
Platform, which provides, during being spliced merges addition line, addition pinching point, extraction subarc section, addition control
A series of interactive modeling tools such as line, generation lenticular body, intersection cutting, for interactive modeling under three-dimensional environment.
After all being generated when geology face, it is possible to form geological mass.An empty geologic body is created first, selects phase
The stratum number answered, is then added to corresponding geology face in the block with cross-sectional area, just forms the geology of a closing
Body.
We use improved modeling method.The difference that its geologic body is formed has:
(1)It is expanded to from less parallel section with level(Geologic map)Geological boundary is frame, using route section as constraint,
Automatically according to the body that horizontal geological boundary face is formed, according to the geological boundary experiment material geologic body depth side in depth profiled direction
To form and relationship, automatically form body.Geology is determined according to the geological boundary form and relationship in depth profiled direction simultaneously
The logical relation of body, volcanic crater ring center position as shown in figure 17 cut through peripheral geologic body.
Key technology further includes:Using the geological boundary block integral side under more intersecting routes sections and occurrence constraint
Method, thus it is speculated that go out the continuously and three-dimensionally matter boundary line of the following layering of earth's surface.It is also the technological core of the present invention.
Establish the refined model of three-dimensional geologic using block integral method, key be according to surface geology boundary line,
The route section and earth's surface of comprehensive study have under the constraint of occurrence point, and the precision and step pitch of block integral are determined according to engineer's scale,
It is successively inferred to continuous underlying geological boundary line down.Route section more subtly can reflect geological personnel rule of thumb
The subsurface formations situation of deduction.N intersecting routes section generally can determine that constraint is inferred in 2n lower section stratified formations boundary line
Point according to these obligatory points, using curve fitting technique, can calculate layering geological boundary, pass through triangular facet between each layer
Construction method forms geological interface.It should be noted that the form of geological boundary is not only constrained by section, while by occurrence point about
Beam, the plane how occurrence point information is attached to polygon are estimated in fitting, finally deducing the company being layered below earth's surface
Continuous three-dimensional geological boundary line.
(2)4th is coating, the processing procedure of vein.
4th is that coating will be independent stratum, is built with other stratigraphic divisions.Wherein, the 4th is dividing for coating
Cloth range is obtained from geologic map, and thickness is obtained from comprehensive caliper log figure.Although the covering of the 4th system of different location
Thickness is different, but because data are limited, the stratum that the structures of all Quaternary Stratas will be obtained from comprehensive caliper log figure
Thickness is as average thickness(It can be recorded the thickness as an attribute field of stratigraphic region in geologic map), then to two
Infer side.For Quaternary Strata, using polygon focus point/center of mass point as the maximum gauge of Quaternary Strata, then to two
Side deduction, gradual pinching;Its bottom surface will be consistent with surface relief substantially, a few point can be fixed, directly from landform
Inferred, other positions point is obtained by interpolation, and interpolation method may be selected apart from inverse ratio, than batten etc..
In a manner that geologic map and geological map of bed rocks constrain jointly, Quaternary Strata is removed, and there can be foundation
Judgement the 4th be infratectal basement rock distribution situation.
By Quaternary Strata the Seal treatment of section situation, as shown in figure 18.
The disposition that Quaternary Strata is removed, as shown in figure 19.
Step 17:The step of ultimately producing three-dimensional geological figure.
On the basis of step 16,3D geologic maps are formed, as shown in figure 20.Meanwhile also provide the explosion analysis of model, mould
The dragging analysis tool of type and region-wide geology body three-dimensional models topological coherence detection instrument.
In techniqueflow research, a kind of hand using model topology consistency detection technology as analysis modeling precision is needed
Section and tool, and incorporate in three-dimensional modeling flow.Topological coherence is examine three-dimensional geological modeling quality and correctness one
No matter major criterion which kind of threedimensional model and the three-dimensional geological body Model of corresponding modeling method foundation taken, does not allow to exist
Adjacent geologic body has overlapping or separation situation.Be limited by limited modeling data source and model area in initial data it is close
Degree and the heterogencity of quality(Geologic body as occurrence point is uneven, route section influences is limited)Even if same survey area
The model of geological structure body that different modeling methods is used to establish different piece is inside also needed, modeling fine degree may cause to be adjacent to
The topological nonuniformity in the public face of plastid.Therefore, topology detection is carried out to geologic body threedimensional model with correcting, avoids single geology
Body self intersection, and ensure the topological coherence in the adjacent public face of geologic body.
The geotraverse of the present invention(PRB)The method that Data fuse generates three-dimensional geological figure, can also use comparative maturity
Profile Modeling method, the Geologic modeling based on section can be divided into four basic processes:
First, the pre-treatment step of model data (cross-sectional data being linked to be between borehole data or drilling).
Here, the pre-treatment step be necessary condition, otherwise can not generate, geologic mapping is no drilling, this be with
The difference of former three-dimensional modeling method maximum.
Second, the step of definition of section, explanation are with delineation and generation.
