Description

Technical Field

[0001] The present invention relates to the field of three-dimensional modeling, and in particular to a method, device, equipment and storage medium for establishing a geological three-dimensional model. Background Art

[0002] Shield tunneling has been widely used in tunnel construction in recent years. In some complex geological conditions, the shield machine must traverse multiple strata during construction. In soft soil areas, some strata are largely discontinuous due to repeated erosion and sedimentation. Some of these strata present unfavorable geological conditions for tunnel construction and operation, such as high water content, susceptibility to disturbance, and the risk of quicksand. Therefore, prior to construction, it is crucial to clearly understand the specific strata traversed by each tunnel loop so that various contingency plans can be prepared to ensure safe construction.

[0003] Currently, borehole data is required for 3D geological modeling. However, the acquisition cost of borehole data is high. The number of boreholes obtained for a regional study will be very limited, and the coverage density will be low.

[0035] Example 1

[0036] Figure 1 A flowchart of a method for establishing a geological three-dimensional model is provided for the first embodiment of the present invention. This embodiment is applicable to the case of establishing a geological three-dimensional model for a geological region. The method can be executed by a geological three-dimensional model establishment device. The geological three-dimensional model establishment device can be implemented in the form of hardware and / or software. The geological three-dimensional model establishment device can be configured in a computer. Figure 1 As shown, the method includes:

[0037] S110 , obtaining sample soil layer data at a designated soil layer position in a geological area, and establishing an initial geological three-dimensional model based on the sample soil layer data.

[0038] A geological region refers to the area that requires exploration to establish a 3D geological model. A soil layer refers to the layers within a soil profile that have varying morphological characteristics and are generally horizontal, also known as the soil formation layer. A designated soil layer location refers to a user-specified soil layer. A user is the person conducting geological exploration. Sample soil layer data refers to the original drill hole data at a designated soil layer location within a geological region. A geological 3D model is a digital representation of a geological body, demonstrating the structural relationships between soil layer data within the geological region.

[0039] Figure 2 A flowchart of a method for establishing a geological three-dimensional model is provided for the first embodiment of the present invention. Step S110 mainly includes the following steps S111 to S114:

[0040] S111. Obtain sample soil layer data at a designated soil layer position in a geological area.

[0041] Optionally, obtaining sample soil layer data at a specified soil layer position in a geological area includes: obtaining original drilling data at a specified soil layer position in the geological area, wherein the original drilling data includes coordinate position and rock and soil name; and converting the original drilling data into a specified format based on ArcMap software to generate sample soil layer data.

[0042] Specifically, the controller will obtain the original drilling data at the specified soil layer position in the geological area. The original drilling data includes the coordinate position and the rock and soil name. The coordinate position is expressed in the form of (x, y, z). The rock and soil name refers to the type of soil in the soil layer. The rock and soil names include coarse granular fill, clay fill, coarse gravel sand, and fully weathered conglomerate zone. The controller will organize the original drilling data into a table. The following Table 1 shows an example of the obtained original drilling data:

[0043] Table 1

[0044] Serial number Drill hole number x-coordinate y coordinate z coordinate Geotechnical name 1 A1 40508759.33 4002493.26 4.27 Coarse-grained fill 2 A1 40508759.33 4002493.26 4.29 Clay soil fill … … … … … … 9 A1 40508759.33 4002493.26 4.32 coarse gravel sand 10 A1 40508759.33 4002493.26 4.29 Fully weathered conglomerate zone

[0045] Taking serial number 1 as an example, the original borehole data corresponding to serial number 1 is borehole number A1, the x-coordinate is 40508759.33, the y-coordinate is 4002493.26, the z-coordinate is 4.27, and the geotechnical name is coarse-grained fill. Of course, this embodiment is merely an example and does not limit the number and type of the collected original borehole data. Furthermore, the controller converts the original borehole data into a specified format based on ArcMap software to generate sample soil layer data. ArcMap software is used in the field of tunnels and underground engineering for three-dimensional visual geological modeling. The use of three-dimensional visualization technology allows geologists to have a more intuitive understanding of the spatial morphological characteristics of geological bodies during the survey process, making up for the shortcomings of traditional two-dimensional geological analysis, making the analysis results more objective and accurate, and playing an important auxiliary role in promoting the progress of geological work. For example, the controller can add the acquired original borehole data table to ArcMap 10.0 software and convert the borehole data into a point feature file in ".shp" format using the "AddXYData" tool.

[0046] S112 . Pairing the sample soil layer data to generate paired data, wherein the paired data includes sample soil layer data at two specified distances.

[0047] Optionally, each sample soil layer data is paired to generate paired data, including: determining the layer position of each sample soil layer data according to the rock and soil name; determining the distance between each two sample soil layer data contained in each layer position according to the coordinate position; and using the sample soil layer data corresponding to the specified distance as paired data.

[0048] Specifically, when performing variation analysis, the controller needs to model the spatial structure of the measurement points, starting with the graph of the empirical semivariogram, and calculating the semivariogram value for all position pairs separated by a specified distance. First, the controller will pair the sample soil layer data to generate paired data. When generating paired data, it is necessary to determine the layer position of each sample soil layer data according to the rock and soil name, and then determine the distance between each two sample soil layer data contained in each layer position according to the coordinate position. Then, the two sample soil layer data corresponding to the specified distance are taken as a set of position pairs, namely paired data.

[0049] S113. Calculate the semivariogram value of each paired data.

[0050] Optionally, calculating the semivariogram value of each paired data includes: taking the coordinate position of the sample soil layer data contained in the paired data as the paired coordinate; and taking half of the square of the difference between the paired coordinates as the semivariogram value.

[0051] Specifically, the controller uses the coordinate positions of the sample soil layer data contained in the paired data as the paired coordinates, and then uses half of the square of the difference between the paired coordinates as the semivariogram value. Furthermore, since the distance between each paired data point is unique and there are many point pairs, it becomes difficult to quickly plot all the paired data points. Therefore, instead of plotting each paired data point, the paired data points are grouped into bins of various step sizes and then the empirical semivariogram graph is plotted. Figure 3 A schematic diagram of an empirical semivariogram image is provided for this embodiment. Figure 3 In the figure, each dot represents the semivariogram value of each paired data, the horizontal axis represents the distance of the paired data, and the vertical axis represents the semivariogram, that is, the average semivariogram value.

[0052] S114 , obtaining a modeling function input by the user, and modeling the semivariogram value and the sample soil layer data according to the modeling function to generate an initial geological three-dimensional model.

[0053] Specifically, the modeling function refers to the function used to model the empirical semivariogram, including trigonometric functions, spherical functions, exponential functions, Gaussian functions, and linear functions. The semivariogram values ​​and sample soil layer data are then modeled according to the modeling function to generate an initial geological three-dimensional model. The selected modeling function will affect the prediction of unknown values, especially when the shape of the curve near the origin is significantly different. The steeper the curve near the origin, the greater the influence of the closest adjacent elements on the prediction, and the less smooth the output surface will be. Each modeling function is used to fit different types of phenomena more accurately. For example, taking the spherical model as an example, the model shows a process in which the spatial autocorrelation gradually decreases (equivalent to an increase in the semivariance) to zero after exceeding a certain distance.

[0054] S120: Acquire the position of the soil layer to be measured in the geological area, and determine predicted soil layer information of the position of the soil layer to be measured based on the sample soil layer data.

[0055] Specifically, after identifying the correlation or autocorrelation in the soil layer data and completing the initial data application (i.e., establishing the initial 3D geological model), the fitted model can be used for prediction. Furthermore, regardless of the empirical semivariogram, the controller can obtain the location of the soil layer to be measured in the geological region and determine the predicted soil layer information for the location of the soil layer to be measured based on the sample soil layer data. For example, the Kriging method can be used to generate weights based on the sample soil layer data surrounding the location of the soil layer to be measured to determine the elevation of the location of the soil layer to be measured, thereby generating predicted soil layer information. The predicted soil layer information refers to the x, y, and z coordinates of the location of the soil layer to be measured.

[0056] S130: Establish a final geological three-dimensional model that matches the geological region based on the initial geological three-dimensional model and the predicted soil layer information.

[0057] Optionally, a final geological three-dimensional model matching the geological region is established based on the initial geological three-dimensional model and the predicted soil layer information, including: constructing an interpolation surface corresponding to the geological region based on the initial geological three-dimensional model and the predicted soil layer information; and performing three-dimensional geological modeling based on the interpolation surface to generate the final geological three-dimensional model.

[0058] Specifically, the controller uses ArcMap 10.0 software to perform semivariogram analysis on the soil layer data obtained from the borehole information. Kriging interpolation is then used to predict the soil layer information at the location of the soil layer to be measured. An interpolation surface corresponding to the geological region is then constructed based on the initial 3D geological model generated by the semivariogram and the predicted soil layer information. Finally, 3D geological modeling is performed in ArcMap 10.0 based on the interpolation surface to generate the final 3D geological model.

[0059] The technical solution of the embodiment of the present invention establishes an initial geological three-dimensional model by acquiring sample soil layer data at a specified soil layer position in a geological area, and then further determines the predicted soil layer information of the soil layer position to be measured based on the sample soil layer data. Finally, a final geological three-dimensional model is established based on the initial geological three-dimensional model and the predicted soil layer information. The demand for drilling data is low, which saves costs. The final geological three-dimensional model is jointly constructed by the initial geological three-dimensional model and the predicted soil layer information, thereby improving the accuracy of modeling.

[0060] Example 2

[0061] Figure 4 This is a flowchart of a method for establishing a geological three-dimensional model provided in the second embodiment of the present invention. This embodiment adds a specific process of determining the predicted soil layer information of the position of the soil layer to be measured based on the sample soil layer data on the basis of the above-mentioned first embodiment. Among them, the specific contents of steps S210 and S230 are roughly the same as those of steps S110 and S130 in the first embodiment, so they will not be repeated in this embodiment. Figure 4 As shown, the method includes:

[0062] S210 , obtaining sample soil layer data at a designated soil layer position in a geological region, and establishing an initial geological three-dimensional model based on the sample soil layer data.

[0063] Optionally, obtaining sample soil layer data at a specified soil layer position in a geological area includes: obtaining original drilling data at a specified soil layer position in the geological area, wherein the original drilling data includes coordinate position and rock and soil name; and converting the original drilling data into a specified format based on ArcMap software to generate sample soil layer data.

[0064] Optionally, an initial geological three-dimensional model is established based on the sample soil layer data, including: pairing each sample soil layer data to generate paired data, wherein the paired data includes sample soil layer data at two specified distances; calculating the semivariogram value of each paired data; obtaining a modeling function input by the user, and modeling the semivariogram value and the sample soil layer data according to the modeling function to generate an initial geological three-dimensional model.

[0065] Optionally, each sample soil layer data is paired to generate paired data, including: determining the layer position of each sample soil layer data according to the rock and soil name; determining the distance between each two sample soil layer data contained in each layer position according to the coordinate position; and using the sample soil layer data corresponding to the specified distance as paired data.

[0066] Optionally, calculating the semivariogram value of each paired data includes: taking the coordinate position of the sample soil layer data contained in the paired data as the paired coordinate; and taking half of the square of the difference between the paired coordinates as the semivariogram value.

[0067] S220: Obtain the position of the soil layer to be measured in the geological area.

[0068] S230 , determining target soil layer data that matches the position of the soil layer to be measured according to the horizontal and vertical coordinates of the position of the soil layer to be measured and the coordinate position of the sample soil layer data.

[0069] S240: Perform Kriging interpolation on the data of each target soil layer to generate a predicted height of the position of the soil layer to be measured.

[0070] S250: Generate predicted soil layer information according to the predicted height and the horizontal and vertical coordinates, wherein the predicted soil layer information includes the coordinate position of the soil layer to be measured.

[0071] Specifically, the controller will obtain the position of the soil layer to be measured in the address area. The position of the soil layer to be measured refers to a position point where the horizontal and vertical coordinates of the soil layer to be measured are known but the elevation information of the soil layer to be measured is unknown. Then, the target soil layer data matching the position of the soil layer to be measured is determined based on the horizontal and vertical coordinates of the soil layer to be measured and the coordinate position of the sample soil layer data. The target soil layer data refers to the sample soil layer data around the position of the soil layer to be measured. The user can determine the target soil layer data by setting a specified range. The controller will determine the target soil layer data within the specified range based on the horizontal and vertical coordinates of the soil layer to be measured and the coordinate position of the sample soil layer data. Then, Kriging interpolation is performed on each target soil layer data to generate a predicted height of the soil layer to be measured. Kriging interpolation refers to the spatial autocovariance optimal interpolation method, which is a very useful geological statistical gridding method. Since Kriging interpolation is an existing technology, the process of Kriging interpolation prediction is not specifically described in this embodiment. Finally, the predicted height is combined with the horizontal and vertical coordinates of the soil layer to be measured to determine the coordinate position of the soil layer to be measured, and then the coordinate position is used as the predicted soil layer information.

[0072] S260: Establish a final geological three-dimensional model that matches the geological region based on the initial geological three-dimensional model and the predicted soil layer information.

[0073] Optionally, a final geological three-dimensional model matching the geological region is established based on the initial geological three-dimensional model and the predicted soil layer information, including: constructing an interpolation surface corresponding to the geological region based on the initial geological three-dimensional model and the predicted soil layer information; and performing three-dimensional geological modeling based on the interpolation surface to generate the final geological three-dimensional model.

[0074] The technical solution of the embodiment of the present invention establishes an initial geological three-dimensional model by acquiring sample soil layer data at a specified soil layer position in a geological area, and then further determines the predicted soil layer information of the soil layer position to be measured based on the sample soil layer data. Finally, a final geological three-dimensional model is established based on the initial geological three-dimensional model and the predicted soil layer information. The demand for drilling data is low, which saves costs. The final geological three-dimensional model is jointly constructed by the initial geological three-dimensional model and the predicted soil layer information, thereby improving the accuracy of modeling.
