[0002] With the rapid development of transportation, tunnel projects are increasing continuously. Before tunnel construction, it is often necessary to construct a building information model to assist tunnel construction. Currently, when constructing a building model, the commonly adopted method is to disassemble and classify the models of the entire project using existing drawing data, parameterize the models of the same type, and further assemble a building information model through a program.

[0003] However, the inventors found that when using the above method for tunnel construction modeling, the following technical problems often exist: The constructed building information model does not incorporate geological data, making it difficult to provide good reference for tunnel excavation construction and difficult to timely feedback the progress of tunnel excavation construction.

[0018] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information. The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0019] Figure 1 Flow 100 of some embodiments of a tunnel construction modeling method applied to tunnel construction according to the present disclosure is shown. The tunnel construction modeling method applied to tunnel construction includes the following steps: Step 101, obtain remote sensing images and digital elevation models.

[0020] In some embodiments, the execution subject (e.g., an electronic device) of the tunnel construction modeling method applied to tunnel construction can obtain remote sensing images and digital elevation models in a wired or wireless manner. Among them, the above remote sensing images capture images of the construction area, and the above digital elevation models may include elevation information of the above construction area. Here, the remote sensing images can be images of the construction area taken by a satellite. The elevation information can be the vertical height values of each ground coordinate.

[0021] Step 102, register the remote sensing images and digital elevation models to generate a three-dimensional digital model, and mark the construction area and the construction peripheral area in the three-dimensional digital model.

[0022] In some embodiments, the above execution subject can register the above remote sensing images and the above digital elevation models to generate a three-dimensional digital model, and mark the above construction area and the above construction peripheral area in the above three-dimensional digital model. Here, through registration, the remote sensing images and the digital elevation models can be fused to improve the accuracy of the model.

[0023] In some alternative implementation manners of some embodiments, the above execution subject registers the above remote sensing images and the above digital elevation models to generate a three-dimensional digital model, including: The first step, according to the resolution of the above remote sensing images, adjust the grid resolution of the above digital elevation model to obtain an adjusted digital elevation model. Among them, if the original resolution of the digital elevation model is lower than the resolution of the above remote sensing images, the grid resolution of the above digital elevation model can be adjusted by resampling. Through resampling, the terrain details of the digital elevation model can be retained, and at the same time, by matching the image size, the surface spectral features (e.g., texture features) of the remote sensing images can be incorporated into the digital elevation model to further improve the accuracy of its texture features.

[0024] As an example, algorithms such as TIN (Triangulated Irregular Network) or Kriging interpolation method can be used for resolution adjustment. For example, register a digital elevation model with a grid granularity of 10m and a remote sensing image with a resolution of 1m, and at the same time use bilinear interpolation or cubic convolution algorithm to optimize the continuity of elevation data to further improve the accuracy of the adjusted digital elevation model.

[0025] In the second step, feature matching is performed on the above remote sensing image and the above adjusted digital elevation model to generate a three-dimensional digital model. Specifically, first, the contour lines of the above adjusted digital elevation model can be extracted through a contour tracing algorithm. Then, the corner points and edge features in the remote sensing image can be extracted. After that, each contour line is matched with the corner points and edge features of the remote sensing image to perform an affine transformation on the remote sensing image, obtaining a transformed remote sensing image. Here, the affine transformation can correct the remote sensing image based on the digital elevation model, eliminate the image displacement caused by factors such as terrain and shooting, and generate an orthographic projection image with more accurate actual geographical location coordinates. Finally, the texture features, color features, etc. of the transformed remote sensing image can be added to the above adjusted digital elevation model to obtain a three-dimensional digital model.

[0026] In some optional implementation manners of some embodiments, the above execution subject marks the construction area and the construction peripheral area in the above three-dimensional digital model, including: In the first step, each construction area boundary coordinate in the pre-marked construction area boundary coordinate set is converted into the above three-dimensional digital model to obtain a converted construction area boundary coordinate set. Among them, each converted construction boundary coordinate in the above converted construction boundary coordinate set represents the construction area boundary. In practice, the construction boundary coordinates can be the coordinates on the pre-marked construction area boundary. Secondly, through coordinate transformation, the construction area boundary coordinates can be converted from the remote sensing image into the above three-dimensional digital model to obtain a converted construction area boundary coordinate set.

[0027] In the second step, the area within the above construction area boundary in the above three-dimensional digital model is marked as the construction area, and the area outside the above construction area boundary in the above three-dimensional digital model is marked as the construction peripheral area.

[0028] As an example, refer to Figure 2 . Figure 2 shows a top view of marking the construction area and the construction peripheral area. Among them, the thick black solid lines on both sides of the construction area are the construction area boundaries. The thick black dashed lines on both sides of the peripheral construction area can be the boundaries of the construction peripheral area. The area enclosed by the thick black dashed lines, excluding the construction area, is the construction peripheral area.

[0029] Step 103, respectively locate the geological drilling coordinates in the construction area and the construction peripheral area in the three-dimensional digital model to obtain a set of geological drilling coordinates.

[0030] In some embodiments, the above-mentioned execution entity may respectively locate geological drilling coordinates in the construction area and the construction peripheral area in the above-mentioned three-dimensional digital model to obtain a set of geological drilling coordinates. Among them, the set of geological drilling coordinates in the three-dimensional digital model is sent to the drilling terminal for geological drilling of the above-mentioned construction area and the above-mentioned construction peripheral area. Here, through geological drilling, it can be used to provide geological information for the above-mentioned three-dimensional digital model, so that the three-dimensional digital model can provide more comprehensive data references for tunnel construction. Improve the tunnel excavation efficiency and safety level.

[0031] In some alternative implementation manners of some embodiments, the above-mentioned execution entity respectively locates geological drilling coordinates in the construction area and the construction peripheral area in the above-mentioned three-dimensional digital model to obtain a set of geological drilling coordinates, including: First step, perform dense grid division on the construction area in the above-mentioned three-dimensional digital model to obtain a grid map of the divided construction area. Among them, a preset dense grid size (such as 0.2 kilometers) can be used to horizontally divide the above-mentioned three-dimensional digital model to obtain a grid map of the divided construction area. Here, the grid map of the divided construction area can be a two-dimensional plan view corresponding to the orthographic top view of the above-mentioned three-dimensional digital model. The grid map of the divided construction area can also be a three-dimensional view including elevation information in the above-mentioned three-dimensional digital model.

[0032] Second step, determine the coordinates of each grid intersection point in the grid map of the divided construction area as a set of geological drilling coordinates within the construction area. Among them, the geological drilling coordinates can be two-dimensional coordinates including abscissa and ordinate.

[0033] Third step, perform regional texture detection on the construction peripheral area of the above-mentioned three-dimensional digital model to generate a texture detection map. Among them, regional texture detection can be used to detect the texture features of the terrain in the construction area and the construction peripheral area.

[0034] As an example, regional texture detection can be performed through a regional texture detection algorithm. Here, the regional detection algorithm can include but is not limited to at least one of the following: wavelet transform algorithm, convolutional neural network, linear filter, etc. In addition, considering that the spatial features of the texture still need to be used after extracting the texture features, a regional detection algorithm that causes loss of spatial position information should be avoided.

[0035] Step 4: Perform coordinate interpolation on the texture features in the mesh map of the peripheral area after the above division to obtain an interpolation coordinate set. Among them, through an interpolation algorithm, coordinate interpolation can be performed on the area within a preset range of the texture features in the mesh map of the peripheral area after the above division to obtain a processed texture detection map. In practice, geological situations such as geological fractures and geological faults often exist in the texture feature area. In order to further improve the accuracy of geological data collection, fine-grained drilling is required near geological fractures and geological faults. Therefore, the drilling coordinates near the texture features can be determined by interpolation.

[0036] As an example, the interpolation algorithm can include but is not limited to at least one of the following: linear interpolation algorithm, spline interpolation algorithm, bilinear interpolation algorithm.

[0037] Step 5: Perform sparse grid division on the above texture detection map to obtain a mesh map of the peripheral area after division. Among them, using a preset sparse grid size (such as 0.3 km), perform sparse grid division on the above texture detection map to obtain a mesh map of the peripheral area after division. In addition, during the division process, the area where coordinate interpolation has been performed can be avoided to prevent the coordinates from being too close.

[0038] Step 6: Determine the coordinates of each grid intersection point in the mesh map of the peripheral area after the above division and the interpolation coordinate set as the geological drilling coordinate set for the construction peripheral area, and determine the geological drilling coordinate set for the construction peripheral area and the geological drilling coordinate set within the construction area as the geological drilling coordinate set.

[0039] In practice, considering that the three-dimensional digital model is established for tunnel construction, when extracting geological data, it is necessary to determine the geological conditions within the tunnel construction area as much as possible. Therefore, the construction area and the non-construction area are divided. Here, the construction area is the area involved in the pre-planned construction. Therefore, dense grid division is performed on the construction area, so that fine-grained and uniform geological drilling can be carried out in the construction area to extract more comprehensive geological data. In addition, considering that the non-construction area still has an associated impact on the construction area (such as natural phenomena such as landslides and the amount of underground water seepage), geological drilling is still required for the non-construction area. However, considering that the non-construction area is large and dense geological drilling is not required, sparse grid division is performed on the non-construction area. Thus, the number of geological drillings can be reduced, the construction period can be shortened, and the waste of drilling resources can be reduced.

[0040] Step 104: Use the obtained geological drilling data set to fill the three-dimensional digital model with geological data to generate a three-dimensional geological simulation model.

[0041] In some embodiments, the above-mentioned execution entity may use the obtained geological drilling data set to fill the geological data in the above-mentioned three-dimensional digital model to generate a three-dimensional geological simulation model. Among them, the construction area drilling hole coordinate set and the construction periphery drilling hole coordinate set are marked in the above-mentioned three-dimensional geological simulation model.

[0042] In some alternative implementation manners of some embodiments, each geological drilling data in the above-mentioned geological drilling data set includes a geological information sequence, and each geological information includes a depth value interval of a geological attribute. The above-mentioned execution entity uses the obtained geological drilling data set to fill the geological data in the above-mentioned three-dimensional digital model to generate a three-dimensional geological simulation model, including: The first step is to obtain the three-dimensional geological data detected by the geological exploration equipment. Among them, the above-mentioned three-dimensional geological data may be public geological data corresponding to the above-mentioned construction area.

[0043] As an example, the above-mentioned geological attributes may include, but are not limited to, at least one of the following: rock, structure, density, fault, etc. The above-mentioned geological information sequence may be arranged according to the depth of the underground drilling samples drilled geologically. For example, [soil layer: 0 - 1 meter, transition layer: 1 - 10 meters, weathered layer: 10 - 30 meters, bedrock layer: 30 - 150 meters].

[0044] The second step is to use the geological information sequence included in each geological drilling data in the above-mentioned geological drilling data set to update the above-mentioned three-dimensional geological data to obtain the updated three-dimensional geological data. Among them, the depth value interval in the geological information is used to calibrate the three-dimensional geological data. First, the position corresponding to each geological drilling data in the above-mentioned three-dimensional geological data can be determined. Then, the geological data at this position can be adjusted by using the geological information sequence included in the geological drilling data. For example, the three-dimensional geological data is public data, but over time, the geological data will have data offsets due to crustal movement and internal effects, such as bedrock layer fractures. Therefore, the three-dimensional geological data can be adjusted according to the arrangement order in the geological information sequence. Finally, taking the adjusted three-dimensional geological data of each coordinate point as a reference, the data in other regions of the three-dimensional geological data can be smoothed by using the locally weighted regression algorithm or the Kriging interpolation method to obtain the updated three-dimensional geological data. Thus, the calibration of the three-dimensional geological data is completed.

[0045] The third step is to fill the above-mentioned updated three-dimensional geological data into the above-mentioned three-dimensional digital model to obtain a three-dimensional geological simulation model. Among them, it can be filled into the above-mentioned three-dimensional digital model according to the height value and the corresponding coordinates of the three-dimensional geological data to obtain a three-dimensional geological simulation model.

[0046] Step 105, plan the tunnel construction route in the three-dimensional geological simulation model to obtain the planned tunnel construction route information.

[0047] In some embodiments, the above-mentioned execution entity may plan a tunnel construction route in the above-mentioned three-dimensional geological simulation model to obtain the planned tunnel construction route information.

[0048] In some optional implementation manners of some embodiments, the above-mentioned execution entity plans a tunnel construction route in the above-mentioned three-dimensional geological simulation model to obtain the planned tunnel construction route information, including: First step, determine the coordinates of the tunnel entrance point and the coordinates of the tunnel exit point. Among them, the above-mentioned three-dimensional geological simulation model can be displayed on a display terminal, and the coordinates of the tunnel entrance point and the coordinates of the tunnel exit point in the three-dimensional geological simulation model input manually by a human can be obtained.

[0049] Second step, in the above-mentioned three-dimensional geological simulation model, mark the constructible area between the above-mentioned coordinates of the tunnel entrance point and the above-mentioned coordinates of the tunnel exit point. Among them, the geological areas with construction risks in the geological data can be pre-marked as obstacle areas. For example, fault risks, karst cave risks, etc.

[0050] Third step, according to the preset tunnel construction size, plan the construction route for the above-mentioned constructible area to obtain the construction planned route. Among them, the tunnel construction size is the tunnel construction diameter. The shortest distance line where the shortest distance between the above-mentioned coordinates of the tunnel entrance point and the above-mentioned coordinates of the tunnel exit point is located can be determined by a path planning algorithm. In addition, during the path planning process, the marked obstacle areas can be avoided.

[0051] As an example, the above-mentioned path planning algorithm may include but is not limited to at least one of the following: A* algorithm, Genetic Algorithm (GA), or Dijkstra algorithm, etc.

[0052] Fourth step, determine the above-mentioned construction planned route, the above-mentioned coordinates of the tunnel entrance point, and the above-mentioned coordinates of the tunnel exit point as the planned tunnel construction route information.

[0053] Step 106, send the planned tunnel construction route information to each construction terminal for tunnel construction, and synchronize the construction monitoring data of each construction terminal to the three-dimensional geological simulation model as a tunnel construction model.

[0054] In some embodiments, the above-mentioned execution entity may send the above-mentioned planned tunnel construction route information to each construction terminal for tunnel construction, and synchronize the construction monitoring data of each construction terminal to the above-mentioned three-dimensional geological simulation model as a tunnel construction model.

[0055] Optionally, the above-mentioned execution entity may further execute the following steps: First step: According to the obtained tunnel route adjustment information, adjust the construction planning route in the above three-dimensional geological simulation model to obtain an adjusted tunnel construction model. Among them, the tunnel route adjustment information can be the route further adjusted by experts based on geological information. Thus, the construction planning route in the three-dimensional geological simulation model can be adjusted according to the tunnel route adjustment information to obtain an adjusted tunnel construction model.

[0056] Second step: Obtain the first construction positioning coordinates output by the positioning device. Among them, the above first construction positioning coordinates are the position coordinates of the center point where the tunnel heading face intersects the ground.

[0057] In addition, considering that the position coordinates of the center point where the tunnel heading face intersects the ground (i.e., the corner position) are more likely to be affected by the positioning interference of the wall and there are limitations for subsequent adjustment of the positioning position, the above first construction positioning coordinates can also be the position where the above center point position coordinates are moved a certain distance (such as two meters) in a certain fixed direction.

[0058] As an example, the positioning device can be a gyroscope longitude and latitude positioning device. Specifically, the position coordinates of the center point can be determined by manual measurement, and then a positioning device is set at this point for positioning. Here, the positioned longitude and latitude coordinates can be converted into three-dimensional coordinates in the three-dimensional geological simulation model.

[0059] Third step: Select geological drilling coordinates that meet the preset azimuth conditions from the above geological drilling coordinate set to obtain the current geological drilling coordinate group. Among them, the above preset azimuth conditions can be at least three geological drilling coordinates closest to the above first construction positioning coordinates to obtain the current geological drilling coordinate group.

[0060] Fourth step: Select the construction route coordinates closest to the above first construction positioning coordinates from the above construction planning route as the route reference coordinates.

[0061] In addition, the displacement vector from the above first construction positioning coordinates to the above route reference coordinates can be determined.

[0062] Fifth step: Determine the first position relationship information between the above current geological drilling coordinate group and the above route reference coordinates. Among them, the three vectors between each current geological drilling coordinate and the above path reference coordinates can be determined as the first position relationship information.

[0063] As an example, refer to Figure 3 . Such as Figure 3As shown, the blue line can be the construction planning route. The red line area can be the excavated tunnel. The point 31 on the tunnel face is the route reference coordinate. The three black coordinate points 32 are the current geological drilling coordinates. Thus, the position of a route reference coordinate can be located through the three current geological drilling coordinates.

[0064] Step 6, obtain the actual route reference coordinate of the positioning device at the position where the above route reference coordinate is located, and determine the first position error between the actual route reference coordinate and the above route reference coordinate. Here, the above displacement vector can be sent to the positioning device end for manually moving the positioning device a fixed distance in the direction indicated by the above displacement vector to reach the actual route reference coordinate.

[0065] Step 7, determine the second position relationship information between the above current geological drilling coordinate group and the above actual route reference coordinate. Among them, the three vectors between each current geological drilling coordinate and the above actual route reference coordinate can be determined as the second position relationship information.

[0066] Step 8, use the above first position relationship information and the above second position relationship information to generate a second position error, and determine the positioning error of the above first construction positioning coordinate according to the above first position error and the above second position error. Among them, the second position error can be generated through the following steps: First, determine the vector modulus length between the two vectors of the corresponding coordinates in the above first position relationship information and the above second position relationship information as the vector position change amount. Here, the two vectors of the corresponding coordinates can be the vectors corresponding to the same current geological drilling coordinate (i.e., corresponding to the same fixed current geological drilling coordinate).

[0067] Then, if the modulus length change of any one vector exceeds the threshold, it is determined that there is a position change between the first position relationship information and the above second position relationship information. That is, there is a position change between the route reference coordinate and the actual route reference coordinate.

[0068] After that, determine the cosine value of the vector included angle between the two vectors of the corresponding coordinates in the above first position relationship information and the above second position relationship information as the vector angle change amount.

[0069] Finally, if the vector angle change amount of any one vector exceeds the preset angle threshold, it is determined that there is a direction change between the two positions before and after (i.e., the route reference coordinate and the actual route reference coordinate). Therefore, it can be characterized that there is an error in the positioning of the positioning device for the same point. Thus, after determining that the vector position and direction have changed, the second position error can be obtained by summing the modulus lengths of each vector according to the corresponding vector angle.

[0070] In addition, the weighted sum of the above-mentioned first position error and the above-mentioned second position error can be determined as the positioning error. Here, the positioning error can correspond to an error direction.

[0071] In the ninth step, using the above-mentioned positioning error, adjust the above-mentioned first construction positioning coordinate to obtain an adjusted construction positioning coordinate. Among them, according to the error direction of the above-mentioned positioning error, the above-mentioned first construction positioning coordinate can be adjusted according to the positioning error to obtain an adjusted construction positioning coordinate. Therefore, an adjusted construction positioning coordinate after correcting the positioning error can be obtained here.

[0072] In the tenth step, in response to determining that the adjusted construction positioning coordinate deviates from the above-mentioned construction planned route by more than a preset threshold, issue a route deviation warning and mark it in the above-mentioned adjusted tunnel construction model.

[0073] In practice, considering that during the construction of a long tunnel, there are often problems with positioning accuracy requirements. However, during the construction of a long tunnel with total station positioning, as the depth increases, it is easy to be blocked between the heading face and the preset monitoring station, resulting in the need to frequently manually adjust the prism for alignment. This leads to measurement azimuth deviation and cumulative errors. GPS-RTK positioning is easily affected by terrain and electromagnetic interference. Triangulation requires the establishment of a high-precision control network and takes a long time to process data. Laser guidance also reduces accuracy due to the increase in tunnel depth and the influence of dust and water mist. Gyroscope positioning also requires regular calibration and has cumulative errors. Therefore, in order to further improve the positioning accuracy, first, introduce the current geological drilling coordinate group as a fixed positioning reference. Then, through the combination of triangulation, measure the positioning error between two coordinates before and after (i.e., the route reference coordinate and the actual route reference coordinate). Thus, the positioning error of the positioning device at the current position can be calculated. Therefore, without laying a large number of positioning devices, cumulative errors can be avoided, and the positioning error of the first construction positioning coordinate can be greatly eliminated. In this way, the position of the lower center point of the heading face of the actual tunnel construction can be determined. Thus, it can be determined whether there is a position deviation. Furthermore, accurate positioning and deviation warning can be made for tunnel excavation.

[0074] In some optional implementation manners of some embodiments, the above-mentioned execution subject sends the above-mentioned planned tunnel construction route information to each construction terminal for tunnel construction, and synchronizes the construction monitoring data of each construction terminal to the above-mentioned three-dimensional geological simulation model as a tunnel construction model, including: In the first step, send the above-mentioned planned tunnel construction route information to each construction terminal for tunnel construction. Among them, the construction terminal can include but is not limited to at least one of the following: shield machine terminal, roadheader terminal, rock drill jumbo terminal, bolter jumbo terminal, concrete spraying terminal, steel arch installation terminal, material transportation terminal, etc.

[0075] Step 2: For the construction monitoring data received from each construction terminal, perform the following steps: Step 1: Classify the above construction monitoring data to obtain a classified monitoring data group. Among them, the data classification can be carried out according to the type of data identifier to obtain a classified monitoring data group. For example, each data identifier can respectively correspond to the above-mentioned construction terminals.

[0076] Step 2: Use the above classified monitoring data group to update the positions of the various simulation facilities preset in the above three-dimensional geological simulation model to obtain an updated three-dimensional geological simulation model. Among them, the device position coordinates in the classified monitoring data can be extracted, and then the corresponding simulation facilities can be adjusted to the position where the above device position coordinates are located. Thus, an updated three-dimensional geological simulation model is obtained.

[0077] Step 3: In response to the classified monitoring data indicating an adjustment of the construction planning route, update the construction planning route in the above updated three-dimensional geological simulation model to obtain a tunnel construction model.

[0078] As an example, if the tunneling machine terminal sends out that "softer shale appears in the front left than originally expected", the construction route needs to be changed. Therefore, the construction planning route can be re-planned and updated from the excavated position to obtain a tunnel construction model.

[0079] In practice, by establishing a tunnel construction model, not only can the excavation progress of the tunnel be accurately positioned and visually displayed, but also the excavation route can be timely adjusted after receiving changes in geological conditions. Thus, the tunnel excavation progress can be greatly improved.

[0080] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: Through the tunnel construction modeling method applied to tunnel construction in some embodiments of the present disclosure, it can provide a good reference for tunnel excavation construction and also timely feedback the progress of tunnel excavation construction. Specifically, the reason why it is difficult to timely feedback the progress of tunnel excavation construction is that the constructed building information model does not combine geological data. Based on this, the tunnel construction modeling method applied to tunnel construction in some embodiments of the present disclosure, considering that the tunnel construction model needs to be constructed based on the actual terrain, obtains remote sensing images and digital elevation models. Among them, the above-mentioned remote sensing images capture images of the construction area, and the above-mentioned digital elevation model includes the elevation information of the above-mentioned construction area.

Then, the above-mentioned remote sensing images and the above-mentioned digital elevation model are registered to generate a three-dimensional digital model, and the above-mentioned construction area and the construction area outside the construction are marked in the above-mentioned three-dimensional digital model. Here, through registration, the remote sensing image can be fused with the elevation digital model, thereby improving the spatial accuracy of the three-dimensional digital model. For the three-dimensional digital model to support decision-making ability during tunnel construction. Next, geological drilling coordinates are respectively located in the construction area and the area outside the construction in the above-mentioned three-dimensional digital model to obtain a set of geological drilling coordinates. Among them, the set of geological drilling coordinates in the three-dimensional digital model is sent to the drilling terminal for geological drilling of the above-mentioned construction area and the area outside the construction. Here, by setting geological drilling, the geological data within the construction area can be further determined. Then, using the obtained set of geological drilling data, the above-mentioned three-dimensional digital model is filled with geological data to generate a three-dimensional geological simulation model, where the above-mentioned three-dimensional geological simulation model is marked with a set of construction area drilling hole coordinates and a set of construction area outside drilling hole coordinates. Here, by introducing geological drilling data, the geological information within the construction area can be fused into the model, resulting in a three-dimensional terrain model. Thus, it is convenient to promote the construction plan in the model. In addition, the tunnel construction route can be planned in the above-mentioned three-dimensional geological simulation model to obtain the planned tunnel construction route information. Here, combined with the geological information in the three-dimensional geological simulation model, it can provide a good construction reference route for the construction party. Thus, it is convenient to carry out tunnel construction. Finally, the above-mentioned planned tunnel construction route information is sent to each construction terminal for tunnel construction, and the construction monitoring data of each construction terminal is synchronized to the above-mentioned three-dimensional geological simulation model as the tunnel construction model. Thus, various data during tunnel construction can be timely feedback through the tunnel construction model.
