Description
METHOD AND APPARATUS FOR ESTABLISHING THREE-DIMENSIONAL (3D)
GEOLOGICAL ENVIRONMENT EVALUATION MODEL FOR UNDERGROUND SPACE, AND7204992
DEVICE
The present disclosure relates to the technical field of geological evaluation and modelling, and in particular to a method and an apparatus for establishing a three-dimensional (3D) geological environment evaluation model for underground space, and a device.
It is a comprehensive issue for evaluation on geological environment of underground space.
The evaluation items should involve geographical location, regional stability, characteristics of rock and soil mass, characteristics of water environment, and especially spatial combination characteristics of the rock and soil mass. The evaluation is very difficult since each evaluation item contains so many indicators that are influenced by a lot of factors. Currently, the evaluation on geological environment of the underground space is mostly based on compilation and collection of chart information. The information is processed manually which has the defects of cumbersome process, large workload, low efficiency, and untimely updating. Non-uniform data formats further cause many inconveniences to subsequent work. Moreover, the underground space is sealed and undeveloped. The characteristics of the geological environment of the underground space cannot be directly presented. Therefore, visualization of the geological environment is needed to provide a more realistic and objective evaluation. This problem can be effectively resolved through 3D geological modelling.
At present, the 3D geological modelling mainly has three types of data structures: a surface model structure, a volume model structure, and a hybrid model structure. The surface model structure is formed by generating a surface using points, which is simple in structure and operation. However, it has a large error in algorithm accuracy, making it difficult to express the internal geological characteristics of a geological body. The volume model structure includes a regular unit body and an irregular unit body. The volume model structure can accurately express the internal geological characteristics of the geological body, and has a spatial analysis capability. However, the calculation efficiency is very low and the error is very great if there if a big amount of data. The hybrid model structure is a combination of a plurality of volume models and surface models. The accuracy in expressing the internal geological characteristics can be improved with the hybrid model structure. However, it is complex in operation, and requires operation personnel to have a comprehensive understanding on the geological environment. In addition, a theoretical technique of the hybrid model structure still needs to be improved.
Software of the 3D geological modelling, such as GOCAD, 3DMINE, and EarthVision, is seldom used in the evaluation on the geological environment of the underground space, while it is mostly used in mining, energy, and other technical fields,. Visual and quantitative big data LU504992 integrated operation and information extraction technologies also need to be fully applied in various fields. The compatibility between software or platforms are poor due to the lack of unified a modelling standard between them. Thus, survey data cannot be directly applied to a model data source, resulting in poor sharing performance. The modelling process of each platform is different with strong professionalism. It is difficult for operation. The calculation and connection between data are imprecise, and the exchange and share between visualization and data in modelling is very poor.
An objective of the present disclosure is to provide a 3D data processing and visualization platform based on Voxler software, which can visually display a distribution of boreholes, a distribution of geological bodies, various types of in-situ tests, geotechnical tests, geophysical data, etc. A Voxler data processing module is used to comprehensively analyse a geological environment of underground space, and a traditional two-dimensional (2D) evaluation method is combined with a 3D module to highlight a geological environment characteristic of each evaluation unit body in the space.

In one embodiment, the comprehensively analysing and evaluating a geological environment for underground space development by using the Voxler platform based on modelling and characterizing results to obtain a comprehensive analysis and evaluation result includes: LU504992 discretizing evaluation space into a 3D grid by using a Gridder module; assigning a property to the 3D grid based on a spatial variation characteristic of each evaluation factor; and calculating, by using a mathematical model for comprehensive evaluation, a plurality of property values attached to the 3D grid, and dividing the calculated property values based on a certain threshold to obtain the comprehensive analysis and evaluation result.
In one embodiment, the displaying the comprehensive analysis and evaluation result in a 3D manner to obtain a 3D geological environment evaluation model for underground space includes: displaying the comprehensive analysis and evaluation result on the Voxler platform in the 3D manner to obtain the 3D geological environment evaluation model for the underground space, where the 3D geological environment evaluation model for the underground space is allowed to be scaled at any scale and observed at any angle; and cutting the 3D geological environment evaluation model for the underground space arbitrarily by using a ClipPlane module, and observing a vertical change characteristic of the evaluation result.
In addition, the present disclosure further provides an apparatus for establishing a 3D geological environment evaluation model for underground space to implement the above method, including: a characterization unit configured to model and characterize a geological interface, a geological body, a borehole, and a geotechnical property by using a Voxler platform based on regional geological environment survey data; an analysis and evaluation unit configured to comprehensively analyse and evaluate a geological environment for underground space development by using the Voxler platform based on modelling and characterizing results to obtain a comprehensive analysis and evaluation result; and a 3D displaying unit configured to display the comprehensive analysis and evaluation result in a 3D manner to obtain a 3D geological environment evaluation model for underground space.

The technical solutions provided by the present disclosure have following beneficial effects:
The Voxler platform is skilled in processing data types in X, Y, Z, and C forms, thus a property value C is assigned to a point in underground 3D space.

The traditional 2D evaluation method is combined with the 3D module to highlight the geological environment characteristic of each evaluation unit body in the space. LU504992
The 3D model constructed according to this method is easy to operate and understand, and has a high accuracy. The 3D model breaks through shortcomings of existing general evaluation on a 2D plane, and is more in line with a 3D change of the geological environment characteristic. 5 Accordingly, the method has a good prospect for promotion and application.

In order to describe the technical features, objectives and effects of the present disclosure more clearly, specific implementations of the present disclosure are described in detail below with reference to the accompanying drawings.
Referring to FIG. 1, the present disclosure provides a method for establishing a 3D geological environment evaluation model for underground space, including following steps:
S1: Model and characterize a geological interface, a geological body, a borehole, and a geotechnical property by using a Voxler platform based on regional geological environment survey data.
S2: Comprehensively analyse and evaluate a geological environment for underground space development by using the Voxler platform based on modelling and characterizing results to obtain a comprehensive analysis and evaluation result.
S3: Display the comprehensive analysis and evaluation result in a 3D manner to obtain a 3D geological environment evaluation model for underground space.
Based on but not limited to the above method, the S1 is specifically implemented according to following substeps:
S11: Modelling and characterizing for the geological interface 1. Import edited data into Surfer (referring to FIG. 1 for an initial data format of the geological interface), and export an interpolation result as a GRD format file. 2. Import the GRD format file directly into the Voxler, and then click a HeightField function in a module manager to connect the HeightField function with the imported GRD format file. 3. Select HeightField in network manager, and adjust a displaying effect of the geological interface in a property manager (as shown in FIG. 3).
It should be noted that both the Surfer and the Voxler are software released by Golden
Software. The Voxler is skilled in processing data of x, y, z, and c types, while the Surfer is skilled in processing data of x, y, and z types (control point data reflecting a morphology of the geological interface is of the x, y, and z types).
In the Voxler and the Surfer, 13 interpolation methods are provided: Kriging interpolation, improved Kriging interpolation, inverse distance weighted interpolation, triangulation with linear interpolation, minimum curvature interpolation, natural neighbor interpolation, nearest neighbor interpolation, local polynomial interpolation, radial basis function interpolation, multivariate regression interpolation, modified Shepard interpolation, data measurement, and moving LU504992 average. An interpolation method should be reasonably selected based on a different geological body.
In this embodiment, the inverse distance weighted interpolation method is preferred. In the inverse distance weighted interpolation method, any observation value has an impact on an adjacent region, and the impact decreases with an increase of a distance. A structure of spatial interpolation can be changed by adjusting a weight. The Kriging interpolation method estimates a value of a spatial variable based on a value of an adjacent variable by using a variation function to reveal an intrinsic connection between regional variables, and its gridding accuracy is high.
S12: Modelling and characterizing for the geological body
Mode 1: A boundary of the geological body displayed by surrounding of the geological interface. Based on a known geological interface, the data of an internal space surrounded by the geological interface is whitened by using a math calculation module (a formula format is
Z>B? 0: A or Z<B? 0: A), and whitened data is finally connected to a VolRender module for exporting and displaying.
Mode 2: Perform displaying through discrete property point interpolation. For example, location and thickness data of a certain stratum exposed by each borehole is known. Based on the known data, interpolation analysis is performed on the data by using a Gridder calculation module, and the data is finally connected to an Isosurface module for exporting and displaying (as shown in FIG. 4).
S13: Modelling and characterizing for the borehole 1. Import collar data: Click am import command, select an edited collar file in an import dialog box (the collar file is in an XLSX format, and an initial data format is shown in FIG. 5), add the data to the network manager, view a property of the data in property manager, and set an output type to wells instead of points in output. 2. Import trajectory data: Specific steps are the same as the above steps. 3. Import sample data: Specific steps are the same as the above steps. 4. Click a well function in the module manager, and connect the well function to the collar, trajectory, and sample data imported in the above steps. 5. Click a WellRender function in the module manager, and connect the WellRender function to well data (BoreholeData shown in FIG. 5) generated in the above step. 6. Select a WellRender file (BoreholeRender shown in
FIG. 3 to FIG. 9), and adjust a displaying effect of the borehole in the property manager (as shown in FIG. 6).
S14: Modelling and characterizing for the geotechnical property
A method for processing point data that reflects the geotechnical property is as follows: 1. importing sorted scattered property data (an initial format of geotechnical property data is shown in FIG. 7) , and setting the output type to the Points instead of the wells in the output of the property manager; 2. clicking a ScatterPlot function in the module manager, and connecting the
ScatterPlot function with point data generated in the above step; and 3. selecting a ScatterPlot 504902 file, and adjusting a displaying effect of a property point in the property manager. Geophysical data in an HDF format can be directly imported into the model.
Based on but not limited to the above method, the S2 is specifically implemented according to following substeps: 1. discretizing evaluation space into a 3D grid by using a Gridder module; 2. assigning a property to the 3D grid based on a spatial variation characteristic of each evaluation factor (theoretically, a larger density of the grid leads to a smoother property change boundary); and 3. calculating (by using a Match operation module), by using a mathematical model for comprehensive evaluation (for example, a weighted sum method), a plurality of property values attached to the 3D grid, and dividing the calculated property values based on a certain threshold to obtain the comprehensive analysis and evaluation result (as shown in FIG. 8).
A gridding process includes: right-clicking a data source, selecting a "Gridding" module in "Calculation Module", and selecting "Start Gridding" or "Re-gridding" in property settings. When a"Gridding" model is added in a contact graph manager, the "gridding" model should be connected to an upstream data source. A property of the "Gridding" model should be set based on a density of a grid data node and a spacing between grid data nodes, and an appropriate interpolation method should be selected.
When duplicate points are combined into a single representative value, a "Filter" module can be used, without a need to re-sort data source data, thereby reducing a duplicate workload.
The "Filter" module is generally to grid the data source data, convert point data in space into a discrete point, and screen plane coordinate data by using a "Filtering" module in a "Math" module to filter data with a large fluctuation and jump, making a surface of the model smooth.
The duplicate point is processed according to following steps: a. Click a data source module in the contact graph manager. b. In a "Calculation" folder of "Module Manager", double-click a "Duplicate Filter" module to add the "Duplicate Filter" module to the network manager. c. Click a "Duplicate Filter" module in the contact graph manager to select the "Duplicate
Filter" module. d. In the property manager, change a "Reserve Data" option to "Median Z". e. In the property manager, input a fixed value as a Z tolerance.
Based on but not limited to the above method, the S3 is implemented as follows:
A final comprehensive analysis and evaluation result can be scaled at any scale and observed at any angle on the Voxler platform. The 3D evaluation result can be cut arbitrarily by using a ClipPlane module, and a vertical change characteristic of the evaluation result is observed. In this way, the 3D geological environment evaluation model for the underground space is constructed (as shown in FIG. 9).
In this embodiment, the 3D geological environment evaluation model for the underground space in the S3 is constructed in detail according to following steps: LU504992 a: According to a traditional evaluation method, select an appropriate evaluation factor and calculate its weight. b: Create a data source to be imported into the Voxler, where the table information includes a borehole number, plane coordinates of the borehole, an elevation, and a score of the evaluation factor. c: Modify a property table of the data source, and modify an output manner to one-to-one correspond to the property table. d: Grid the data source module, and select an evaluation factor 1 for gridding when selecting "Output Content" in a property gridding manager. e: Connect the "Math" module after the gridding, and use gridded data as a parameter A in a mathematical expression. f: Import a topographic map in a research region as a parameter B in the mathematical expression. The expression is changed to "IF Z>B OR Z<C, 0, A" in property manager of a "Math" model. g: Repeat the above operations to complete data processing of evaluation factors 2 and 3, where the above operations describe a data processing method of the evaluation factor 1. h: Apply a new "Math" model to connect gridded modules of the evaluation factors 1, 2, and 3, and take gridded data of the evaluation factors 1, 2, and 3 as parameters A, B, and C in a new "Math" module, where in this case, the mathematical expression is connected to weights of the evaluation factors, and the mathematical expression is in a following form: A* the weight of the evaluation factor 1+B* the weight of the evaluation factor 2+C* the weight of the evaluation factor 3. i: An upstream input terminal of the "Math" module can only connect up to three data sources. If there are more than three evaluation factors, it is only required to repeat the above operations to grid and whiten the evaluation factors, combine processed evaluation factors with weights, distinguish gridded data sources on the input terminal, and fill in the mathematical expression correctly. j: Add a graphic output module after the step f, change a height, an angle, and other properties of the model by using a "Transformation" module, and then perform volume rendering to obtain a spatial assignment model controlled by the score and the weight of the evaluation factor. k: Modify a colour and other properties in property manager of a "Volume Rendering" module.
