[0060] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0061] Figure 1 1 is a flowchart of the implementation of the human-computer interactive karst cave three-dimensional geological BIM modeling method provided by the embodiment of the present invention. Figure 1 As shown in the figure, the human-computer interactive karst cave 3D geological BIM modeling method includes:

[0062] S110, obtaining drilling and geophysical exploration data.

[0063] In the embodiment of the present invention, drilling is a destructive exploration method that uses a drilling rig to drill into the ground, extracts formation cores, and obtains underground rock information through core analysis.

[0064] Geophysical exploration: The full name is geophysical exploration. It is a method of detecting and analyzing underground structures by using the physical properties of the strata (such as density, magnetic permeability, electrical conductivity, etc.) to collect data through geophysical exploration equipment. It is a means of non-destructive detection of strata. Geophysical exploration is carried out by observing and studying the changes in various geophysical fields (such as gravity field, magnetic field, electric field, seismic wave field, etc.).

[0065] Based on the imported geophysical inversion results, including but not limited to commonly used cave geophysical exploration methods: high-density electrical method, transient electromagnetic method, electrical sounding, shallow seismic, cross-hole electromagnetic wave tomography, cross-hole elastic wave tomography, natural source surface wave method and other geophysical exploration methods, human-computer interaction depicts the cave contour and forms a line set. The full name of the line set is the set of polylines, and the polylines are composed of line segments and nodes. The invention splits the line set at the inflection point.

[0066] S120, preprocessing is performed based on the drilling and geophysical exploration data to obtain a vectorized line set.

[0067] Figure 2 This is a schematic diagram of the display after the drilling and geophysical exploration results are imported. Figure 2 As shown in the figure, along the borehole position, the stratum can be divided into three interfaces, namely: 1. The bottom depth of red clay and secondary red clay stratum, 2. The bottom depth of slightly weathered rock stratum, and 3. The bottom depth of karst layer. These three interfaces are displayed in different colors. After the stratum division is completed, the wave velocity image spectrum is drawn according to different colors, and then different graphics are used to represent the rock-soil boundary, limestone, karst development area and red clay, secondary red clay, and complete the display of geophysical exploration results on the computer display interface.

[0068] Figure 3 The following is a schematic diagram showing the vectorization of geophysical exploration results. Figure 3 As shown, in some embodiments, the drilling and geophysical data include: geological exploration drilling stratification data, standard strata of the engineering site, topographic contour map of the engineering site, and geophysical inversion results map; preprocessing is performed based on the drilling and geophysical data to obtain a vectorized line set, including: determining a vectorized line set based on the geophysical inversion results map; wherein the geophysical vectors of the same cave are stored in the same vectorized line set.

[0069] In some embodiments, a vectorized line set is determined based on a geophysical inversion result map, including: if the geophysical inversion result map is in a picture format, then in response to a user's defined operation, the geophysical inversion result map is three-dimensionally positioned and the geophysical inversion result map is position-checked; the geophysical inversion result map is manually drawn to obtain a vectorized line set.

[0070] In the embodiment of the present invention, the image format may include but is not limited to at least one of the following: JPG, PNG, BMP. The three-dimensional spatial positioning of the geophysical inversion result map is specifically: defining the starting coordinates, end coordinates and elevation points (x, y, z) of the section; defining the height of the imported geophysical section map.

[0071] In some embodiments, determining a vectorized line set according to a geophysical inversion result map includes:

[0072] If the geophysical inversion result map is in vector graphics format, the geophysical detection lines in the geophysical inversion result map are read to determine the vectorized line set; in response to the user's definition operation, the geophysical inversion result map is positioned in three-dimensional space.

[0073] In the embodiment of the present invention, the vector graphics format can be DXF, DWG, etc., which is not limited here. Geophysical exploration results files in this format do not need to be vectorized, but it is necessary to obtain the geophysical exploration line plan layout diagram (.DXF, .DWG, etc. format) in advance. Specifically: ① Read the geophysical exploration results; ② Pick up the corresponding geophysical exploration line; ③ Define the starting coordinates, end coordinates and elevation points (x, y, z) of the geophysical exploration profile; Define the height of the imported geophysical exploration profile drawing. Perform statistical management on the geophysical exploration vectorization results of the same cave, that is, store them as the same line set.

[0074] S130, establishing a three-dimensional model of the cave according to the vectorized line set in a human-computer interactive manner.

[0075] In some embodiments, a three-dimensional model of a cave is established based on a vectorized line set in a human-computer interactive manner, including: in response to a user's splitting operation, the vectorized line set is split into an upper surface line set and a lower surface line set of a cave contour; using the upper surface line set and the lower surface line set of the cave contour as constraints to respectively establish an upper surface model of the cave contour and a lower surface model of the cave contour; and performing mutual surface clipping and closing processing on the upper surface model of the cave contour and the lower surface model of the cave contour to obtain a three-dimensional model of the cave.

[0076] Figure 4 This is a schematic diagram showing the upper surface model of the cave. Figure 5 Figure 1 is a schematic diagram showing the lower surface model of the cave. Figure 4 and 5As shown, in some embodiments, the upper surface line set and the lower surface line set of the cave contour are used as constraints to respectively establish the upper surface model of the cave contour and the lower surface model of the cave contour, including: using the upper surface line set of the cave contour as a constraint and responding to the user's modeling operation to define the modeling range of the upper surface model of the cave contour; within the modeling range of the upper surface model of the cave contour, interpolating and fitting the blank points on the upper surface of the cave contour until the model interface and the line set are close to overlap, so as to obtain the upper surface model of the cave contour; using the lower surface line set of the cave contour as a constraint and responding to the user's modeling operation to define the modeling range of the lower surface model of the cave contour; within the modeling range of the lower surface model of the cave contour, interpolating and fitting the blank points on the lower surface of the cave contour until the model interface and the line set are close to overlap, so as to obtain the lower surface model of the cave contour.

[0077] In an embodiment of the present invention, the overlap standard is: interface modeling requires frequent clicking of encryption and fitting commands to generate a mesh surface that meets the mesh density requirements, has a reasonable trend, and is smooth and flat. During the fitting process, obvious changes in the mesh surface morphology can be observed. When the fitting is clicked, the mesh surface morphology does not change significantly, indicating that the interpolation has converged under the current mesh density and is close to overlap. At this time, it means that the outline of the cave model is consistent with the geophysical interpretation results.

[0078] Figure 6 This is a schematic diagram showing the upper and lower surface models of the cave after being cut and closed. Figure 7 This is a schematic diagram showing the results of a single cave. Figure 6 and 7 As shown, in some embodiments, the upper surface model of the cave contour and the lower surface model of the cave contour are mutually clipped and closed to obtain a three-dimensional cave model, including: judging whether the upper surface model of the cave contour and the lower surface model of the cave contour meet the conditions for closing processing; if the conditions for closing processing are met, clipping and deleting the redundant parts of the upper surface model of the cave contour and the lower surface model of the cave contour, and performing grid filling processing to obtain the three-dimensional cave model; if the conditions for closing processing are not met, in response to the user's line drawing operation, outlining the area that does not meet the closing conditions, re-interpolating and fitting in the area, and jumping to the step of judging whether the upper surface model of the cave contour and the lower surface model of the cave contour meet the conditions for closing processing.

[0079] In the embodiment of the present invention, the upper and lower surfaces of the cave can be closed, that is, the conditions for closed processing are met. The process of cutting and deleting the redundant parts is completed manually. Finally, after the grid hole is filled, Figure 7 The three-dimensional model of the cave is shown.

[0080] S140, adjusting the stratigraphic line relationship in the engineering geological section according to geological experience, and establishing a three-dimensional stratigraphic model.

Fig. 9 Schematic diagram of adjusting the display of engineering geological profile for another human-computer interaction. Fig.10 A schematic diagram for adjusting the display of engineering geological profiles through human-computer interaction. Fig.11 It is the karst cave model of the project site. Figure 8-11 As shown, in some embodiments, the stratigraphic line relationship in the engineering geological profile is adjusted according to geological experience to establish a three-dimensional stratigraphic model, including: in response to the user's adjustment operation, the exploration line definition is drawn, and the new and old relationships of each stratum and the main and sub-stratum structure are defined; checking whether there are incorrect stratigraphic sequences and repeated interfaces in the single-hole stratum; checking the stratigraphic line relationship of the profile and the identification of the cave location, and obtaining an adjusted three-dimensional stratigraphic model.

[0082] In an embodiment of the present invention, based on the engineering geological profile in the survey report, human-computer interaction adjusts the stratigraphic line relationship used for modeling in the three-dimensional geological BIM, so that the established three-dimensional stratigraphic model meets the understanding of geological laws. Specifically: ① Check whether the entered drilling data has errors or omissions in the basic data, and review and handle the errors or omissions in the basic data; ② Draw the exploration line definition; ③ Define the new and old relationship of each stratum, the main and sub-stratum structure; ④ Check whether the single-hole stratum has the following two types of problems: incorrect stratigraphic sequence, whether there are repeated interfaces, among which, repeated interfaces in the borehole refer to the existence of more than two stratigraphic interfaces at the same depth in a certain hole. This is a fatal error, which is often caused by errors in the input data, and requires review and post-processing before the profile inspection can be performed. ⑤ Check the stratigraphic line relationship and the identification of the cave location in each section in the two-dimensional section. The errors detected are adjusted accordingly according to the inspection results, and the adjusted three-dimensional stratigraphic model can be obtained.

[0083] S150, generating a high-precision three-dimensional geological BIM model of the cave based on the three-dimensional cave model and the three-dimensional stratum model.

[0084] Fig.12 It is a high-precision 3D geological BIM model of the cave. Fig.12 As shown in the figure, after the karst cave 3D model is established, other 3D stratigraphic models are directly interpolated into the karst cave 3D model using existing algorithms to obtain a high-precision karst cave 3D geological BIM model.

[0085] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
