Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
It is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
Example 1
According to an embodiment of the present invention, there is provided a method for determining a tunnel excavation period, as shown in fig. 1, the method including:
s102, acquiring main line excavation information and inclined shaft excavation information of the tunnel, wherein the main line excavation information comprises surrounding rock grade distribution of the environment where the tunnel is located, and the inclined shaft excavation information comprises inclined shaft excavation parameters of the tunnel;
s104, acquiring excavation indexes of the tunnel, wherein the excavation indexes are used for indicating tunnel excavation speeds corresponding to surrounding rock grades respectively;
and S106, determining the excavation construction period of the tunnel according to the surrounding rock grade distribution of the environment where the tunnel is located, inclined shaft excavation information and excavation indexes.
In the present embodiment, the tunnel is a tunnel planned to be excavated, and is referred to as a tunnel for convenience of description. Because different rock grades correspond to different excavation speeds, the surrounding rock grade distribution of the tunnel needs to be determined before the tunnel is excavated. The surrounding rock is divided into different grades according to the hardness and the stone quality of the surrounding rock, for example, harder marble is set as a V grade, softer limestone is set as a II grade, and the hardness is graded. The above-mentioned classification is only an example, and does not produce any limitation in the present embodiment.
The main line excavation information of the tunnel comprises surrounding rock grade distribution of the environment where the tunnel is located, a flat curve and a longitudinal section height of the tunnel, wherein the flat curve of the tunnel is used for indicating the plane trend of the tunnel, and the longitudinal section height of the tunnel is used for indicating the gradient (namely the longitudinal trend) of the tunnel. Generally, a main line of a tunnel is excavated based on a flat curve of the tunnel, in the excavation process of the tunnel, the main line of the tunnel needs to be excavated, and inclined shafts of the tunnel need to be excavated, generally, one tunnel includes one or more inclined shafts, inclined shaft excavation parameters are different from main line excavation parameters, so that inclined shaft excavation information of the tunnel needs to be acquired separately, and the inclined shaft excavation information includes excavation parameters of the inclined shafts and corresponding inclined shaft information.
Because the surrounding rock grades of the tunnel are distributed more complexly, in the process of determining the tunnel excavation construction period, excavation indexes are required to be obtained, wherein the excavation indexes are used for indicating tunnel excavation speeds respectively corresponding to the surrounding rock grades, for example, the tunnel excavation speed of the surrounding rock with the surrounding rock grade V is 1m per hour, and the tunnel excavation speed of the surrounding rock with the surrounding rock grade II is 2.6m per hour.
It should be noted that, in this embodiment, after determining the surrounding rock grade distribution, the inclined shaft excavation information, and the excavation index of the environment where the tunnel is located, the excavation index of the tunnel is obtained by obtaining the main line excavation information and the inclined shaft excavation information of the tunnel, where the main line excavation information includes the surrounding rock grade distribution of the environment where the tunnel is located, and the inclined shaft excavation information includes the inclined shaft excavation parameter of the tunnel, and where the excavation index is used to indicate tunnel excavation speeds corresponding to the surrounding rock grades, respectively; and determining the excavation construction period of the tunnel according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information and the excavation index. The method achieves the purpose of quickly determining the tunnel excavation period, thereby realizing the technical effects of reducing the drawing process of manually drawing the tunnel excavation period and improving the calculation efficiency of the tunnel excavation period.
Optionally, in this embodiment, the slant well excavation information further includes at least one of: starting and stopping mileage of the inclined shaft, an excavation mode, the number of the inclined shafts and surrounding rock grade distribution of the environment where the inclined shafts are located.
Specifically, the starting and stopping mileage of the inclined shaft, the excavation mode and the surrounding rock grade distribution of the environment where the inclined shaft is located all affect the excavation time of the inclined shaft, in addition, the inclined shaft excavation information also comprises the top raising time of the inclined shaft, and in the actual application process, the top raising time of the inclined shaft needs to be calculated in the construction period calculation process of the inclined shaft.
Optionally, in this embodiment, the excavation indexes include a main line excavation index and an inclined shaft excavation index, where the main line excavation index is used to indicate the main line excavation speed of the tunnel corresponding to the surrounding rock grade, and the inclined shaft excavation index is used to indicate the inclined shaft excavation speed of the tunnel corresponding to the surrounding rock grade. In an actual application scenario, a difference exists between a main line excavation index of a tunnel and an excavation index of an inclined shaft, and therefore the main line excavation index and the inclined shaft excavation index need to be obtained and used for calculating main line excavation time and inclined shaft excavation time respectively.
The excavation index is a core parameter calculated in the tunnel excavation period, and is a tunnel construction progress index table as shown in table 1, wherein various excavation types and excavation speeds corresponding to various surrounding rock grades are listed in the table, and corresponding excavation index parameters are selected according to different excavation types no matter whether the excavation is carried out on the main track or the inclined shaft, so that corresponding excavation time is calculated. The excavation index table is a concrete construction project of tunnel main line or inclined shaft hole forming, and the excavation speed in the comprehensive index is respectively corresponding to the grade of the surrounding rock.
TABLE 1
Optionally, in this embodiment, determining the excavation period of the tunnel according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information, and the excavation index includes: acquiring tunnel through time of the tunnel according to surrounding rock grade distribution of the environment where the tunnel is located, inclined shaft excavation information and excavation indexes; and drawing a tunnel excavation construction period chart according to the tunnel through time. And after the surrounding rock grade distribution of the environment where the tunnel is located, inclined shaft excavation information and excavation indexes are obtained, the overall through time of the tunnel is calculated, and after the through time is obtained, a tunnel excavation construction period map is drawn according to the through time of the tunnel.
Further optionally, in this embodiment, obtaining the tunnel penetration time of the tunnel according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information, and the excavation index includes: acquiring at least two excavation nodes of the tunnel according to the line flat curve in the main line excavation information and the inclined shaft excavation information; determining the port through time between two adjacent excavation nodes of the tunnel; and determining the tunnel penetration time of the tunnel based on all the port penetration times in the tunnel.
Specifically, the calculation of the key time point of tunnel excavation is to determine the core content of the tunnel excavation period, and the key time point of tunnel excavation includes the port through time of opposite ports (tunnel main hole port and inclined shaft port) and the tunnel through time of the whole tunnel. On a tunnel excavation period chart, because an excavation curve of any section of tunnel is a segmented linear function in mathematics, and the intersection point of two curves is difficult to calculate by using a mathematical equation, software adopts a graphical curve and calculates the tunnel through-penetration time by calculating the intersection point of the two curves.
In an example, taking the excavation indexes shown in table 1 as an example, as an optional tunnel excavation period map shown in fig. 2, in the tunnel shown in fig. 2, there is a slant well, in this case, the tunnel has three excavation nodes, the port through time between two adjacent excavation nodes can be obtained based on different excavation indexes, and after the excavation indexes are connected on the period map, the tunnel through time of the whole tunnel can be obtained. It should be noted that, in the excavation process of the inclined shaft, there is a top-raising time, and the excavation of the inclined shaft can be performed only after the top-raising is completed.
Optionally, in this embodiment, the tunnel excavation duration map includes an excavation curve graph, where: the range of the excavation curve graph is the difference between the effective height of the drawing of the tunnel excavation period chart and the preset longitudinal breaking height in the main line excavation information; the tunnel penetration time comprises a sum of at least one port penetration time in the tunnel. Specifically, the tunnel excavation curve diagram is an important component in the tunnel excavation period diagram, the range of the tunnel excavation curve diagram is calculated by subtracting a preset longitudinal-section height from an effective height of a drawing where the tunnel excavation period diagram is located, and the preset longitudinal-section height is obtained according to the longitudinal-section height of the tunnel and a preset proportionality coefficient.
Optionally, in this embodiment, after acquiring the main line excavation information and the inclined shaft excavation information of the tunnel, the method further includes: judging whether the main line excavation information and the inclined shaft excavation information are complete or not; determining the tunnel excavation period according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information and excavation indexes under the condition that a flat curve in the main line excavation information is normal and/or the inclined shaft excavation parameters are normal; otherwise, sending an alarm prompt to prompt that the line data of the tunnel is abnormal.
Optionally, in this embodiment, the longitudinal length of the drawing of the tunnel excavation period map is determined according to the length of the tunnel; and determining the transverse height of the drawing of the tunnel excavation construction period diagram according to the unit time length of the tunnel penetration time and the tunnel penetration time.
Specifically, since the railway tunnel is a strip-shaped structure, the drawing of the standard size cannot be completely provided with all the design contents, and therefore the actual length of the drawing needs to be calculated according to the actual length of the designed tunnel and the drawing scaling factor of the graph. The longitudinal length of the drawing is defined according to the length of the tunnel, and the transverse height of the drawing is defined by the unit time length and the through time of the range excavation calendar. In this embodiment, the horizontal and vertical scale coefficients of the drawing are different, so that the calculation of the drawing sheet actually defines a drawing coordinate system, draws a graph related to time, calculates by using the horizontal scale coefficient of the drawing, draws a graph related to the tunnel length, and calculates by using the vertical scale coefficient of the drawing.
The proportional coefficient calculation method comprises the following steps:
(1) longitudinal scale factor longitudinal scale parameter/map scale;
(2) transverse proportional system: lateral scale parameter/map scale;
the actual drawing length is:
(1) longitudinal length is the actual length/longitudinal proportionality coefficient;
(2) lateral height is the actual height/lateral proportionality factor.
Optionally, in this embodiment, after acquiring the main line excavation information and the inclined shaft excavation information of the tunnel, the method further includes: judging whether the main line excavation information and the inclined shaft excavation information are complete or not; determining the tunnel excavation period according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information and excavation indexes under the condition that a flat curve in the main line excavation information is normal and/or the inclined shaft excavation parameters are normal; otherwise, sending an alarm prompt to prompt that the line data of the tunnel is abnormal.
In one example, after the positive line slip information and the inclined shaft excavation information of the tunnel are acquired, whether the data of the positive line excavation information and the data of the inclined shaft excavation information are normal or not is judged, and if the data are normal, the data are further processed. And sending an alarm prompt under the condition that any one of the main line excavation information or the inclined shaft excavation information has errors or data is lost. The specific warning prompt can only prompt data errors, or can prompt specific errors, namely prompting that the main line excavation information is wrong or prompting that the inclined shaft excavation information is wrong.
According to the embodiment of the invention, the main line excavation information and the inclined shaft excavation information of the tunnel are obtained, the main line excavation information comprises surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information comprises inclined shaft excavation parameters of the tunnel, and excavation indexes of the tunnel are obtained, wherein the excavation indexes are used for indicating tunnel excavation speeds corresponding to the surrounding rock grades respectively; and determining the excavation construction period of the tunnel according to the surrounding rock grade distribution of the environment where the tunnel is located, the inclined shaft excavation information and the excavation index. The method achieves the aim of quickly determining the tunnel excavation period, thereby realizing the technical effects of reducing the drawing process of manually drawing the tunnel excavation period and improving the calculation efficiency of the tunnel excavation period
