Description

Technical Field

[0001] The invention belongs to the technical field of geological section filling and mapping, and relates to a two- and three-dimensional coordinated railway engineering geological section map filling and mapping method and device. Background Art

[0002] The geological objects faced by railway engineering often have complex spatial distribution. Due to the high drilling cost and limited terrain, the sampling data of underground geological body distribution is relatively sparse, resulting in the filling of longitudinal sections and cross sections relying on the inference of geologists or computers. Taking the longitudinal section as an example, in order to draw the geological body boundary on the railway engineering geological longitudinal section, geological professional technicians need to manually connect the layers in the two-dimensional working interface under the longitudinal section view based on discrete exploration and mapping data.

[0003] However, it is difficult to ensure spatial matching between the geological boundaries drawn in the longitudinal section and the same stratigraphic boundaries in the plan view and cross-section view, and it is impossible to guarantee the accuracy and efficiency of the longitudinal section drawing. There are also technical problems such as poor interaction and synchronization between two-dimensional drawings when drawing railway engineering geological section drawings. Summary of the invention

[0004] The present invention overcomes the deficiencies of the above-mentioned prior art and provides a two- and three-dimensional collaborative railway engineering geological section map filling method and device, a method for intercommunication of survey data, two-dimensional mapping software data and three-dimensional modeling platform data, and enters key elements such as terrain, survey data, and two-dimensional basic maps into a database to obtain railway engineering geological longitudinal section maps, cross-section maps, and plan maps distributed in the three-dimensional modeling space. In the three-dimensional modeling space, users can intuitively check the consistency of geological boundary lines and drawn geological bodies in the three maps, and then directly modify the maps with errors. The modified elements are updated to the database in real time, and then reflected in the two-dimensional maps, so as to achieve the purpose of ensuring the consistency between the two-dimensional map results, reducing rework caused by errors in subsequent work, and improving the efficiency of geological section map filling.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: The present invention provides a two-dimensional and three-dimensional coordinated railway engineering geological section drawing method, comprising the following steps: step 1: obtaining a survey database, and forming a terrain surface based on the survey database; step 2: converting the survey database into three-dimensional spatial geological stratification information; step 3: obtaining the drilling data of a virtual borehole according to the three-dimensional spatial geological stratification information, if the drilling data of the virtual borehole is consistent with the section line stratum data, proceeding to the next step, otherwise editing the survey data and recalculating the drilling data of the virtual borehole; step 4: according to the stratification situation revealed by the survey database and the virtual borehole, connecting the corresponding drilling stratification points of each stratum in the target blank section to generate a layer connection result; step 5: displaying the layer connection result in three dimensions, and outputting a two-dimensional section map.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0018] The invention discloses a method for filling in a railway engineering geological section map in a two-dimensional and three-dimensional coordinated manner, comprising the following steps: step 1: obtaining a survey database, and forming a topographic surface based on the survey database; step 2: converting the survey database into three-dimensional spatial geological stratification information; step 3: obtaining the drilling data of a virtual borehole according to the three-dimensional spatial geological stratification information, and if the drilling data of the virtual borehole is consistent with the stratigraphic data of the profile line, proceeding to the next step, otherwise editing the survey data and recalculating the drilling data of the virtual borehole; step 4: according to the stratification conditions revealed by the survey database and the virtual borehole, connecting the corresponding drilling stratification points of each stratum in the target blank section to generate a layer connection result; step 5: displaying the layer connection result in three dimensions, and outputting a two-dimensional section map.

[0019] Before obtaining the survey database, it also includes setting the range of the terrain surface and setting the elevation of the borehole to participate in the surface difference. To set the range of the terrain surface, in the railway engineering geological information management and application system, open CAD, generate a plane map, draw the surface range with polylines, and determine it by setting the range of the generated surface. To set the elevation of the borehole to participate in the surface difference, in the railway engineering geological information management and application system, open the survey meter, and batch set whether the elevation of the hole mouth is involved in the surface interpolation operation. The elevation of the borehole mouth refers to the elevation measurement of the borehole mouth during field exploration and drilling work.

[0020] The borehole elevation may be used as a known data point in the surface interpolation operation. For example, when making spatial predictions of geological features such as groundwater level and underground rock structure, the borehole elevation and its related geological information such as rock thickness and grade can be used as important input data to consider the variability and spatial correlation of the data. When making interpolation predictions of environmental features such as urban surface temperature, humidity, and pollution level, it may mainly rely on the data from ground observation stations without the need for the borehole elevation.

[0021] Secondly, obtain the survey database and form a terrain surface based on the survey database. Specifically, there are four ways: the first is to form a terrain surface based on DEM data; the second is to form a terrain surface based on topographic map and contour data fitting; the third is to form a terrain surface using one-dimensional and two-dimensional data inference; the fourth is to form a terrain surface based on STL data; start the three-dimensional layer connection tool, and the generation terrain surface setting window will pop up, and you can choose one of the methods.

[0022] The terrain surface is formed according to the DEM data. Specifically, click on the DEM data, a window to open the DEM file will pop up, select the DEM data file, and preprocess the data and perform data interpolation to more accurately reflect the terrain characteristics. Preprocessing includes cropping, resampling, and filling holes in the DEM data. Cropping can remove unnecessary areas, resampling can change the resolution of the data, and filling holes can repair the actual parts of the data. Data interpolation uses interpolation methods such as bilinear interpolation and cubic convolution interpolation to process DEM data to generate high-resolution DEM data, which more accurately reflects the terrain characteristics, helps to better understand the characteristics and laws of the terrain, and provides a scientific basis for geological engineering, urban planning, and environmental protection. It should be noted that DEM is a digital elevation model.

[0023] The terrain surface is formed by fitting the topographic map and contour data. Specifically, start the survey software and open the plan to be stored in the survey database. If the plan has not been initialized, it needs to be initialized. Under the plan of the survey software, find and click the "Elevation Point and Contour Store" menu. In the pop-up window, select the layer containing the contour lines and elevation points. Make sure that the selected layer is consistent with the layer in the data file. Specify the range of the contour lines and elevation points to be stored, such as Figure 2 As shown, during the import process, the software will verify and process the data to ensure the accuracy and consistency of the data, and generate a terrain surface based on the contour data in the survey database.

[0024] The terrain surface is formed by inferring one-dimensional and two-dimensional data. The one-dimensional and two-dimensional data include drill holes, measurement points, and two-dimensional profile ground lines. Click on the drill holes and measurement points to pop up the terrain surface option setting window, such as Figure 3 As shown, in the settings window, first select the type of data source. This may include drilling data, measurement point data or other related data sources. If the data source has not been imported, you need to import the data first and ensure the correctness of the data. Select inverse distance weighted interpolation, kriging interpolation, and natural neighbor interpolation to interpolate and generate a terrain surface.

[0025] To generate a terrain surface based on STL data, just select STL data. It should be noted that STL saves surface triangulation data, so it does not support setting the surface range or drilling holes to generate the terrain surface. If you regenerate the terrain surface, the existing terrain surface will be automatically deleted.

[0026] According to the three-dimensional geological stratification information, the drilling data of the virtual borehole is obtained. First, the virtual borehole occurrence is deduced. The occurrence refers to the position of the structural line or structural surface in space, including block and surface. The occurrence of the block refers to its size, shape, position when it was formed and its surrounding relationship; and the occurrence of the surface, that is, the spatial output state of the surface structure, refers to its relationship with the horizontal reference plane and geographic orientation. In the "Engineering Information Table" of the survey software, the rock formation dip (degrees) and rock formation dip (degrees) are interactively set. When calculating the projection hole stratum and deducing the stratum at the intersection of the profile line, the rock formation will take into account the rock formation occurrence trend, such as Figure 4 As shown, the layer lines of the rock formations are drawn according to the apparent dip angle calculated from the azimuth of the section and the attitude of the rock formations.

[0027] After that, the virtual borehole is derived. The projection hole is the stratigraphic distribution information of the virtual borehole at the vertical section line point. The distance between the virtual borehole and the section line should not be too large, especially in areas with complex geological conditions, otherwise the stratigraphic data of the projection hole will be inaccurate. The specific distance is determined by the user according to the actual situation. The following are the principles for generating the stratigraphic layer of the projection hole: soil layer is determined according to the law of stratigraphic deposition; rock layer, if there is an occurrence, is generated according to the occurrence, and if there is no occurrence, it is determined according to the law of genesis; groundwater is extended horizontally.

[0028] If the drilling data of the virtual borehole is consistent with the stratigraphic data of the profile line, the stratification revealed by the survey database and the virtual borehole is used; otherwise, the survey data is edited to recalculate the virtual borehole transfer data, specifically, stratigraphic division, stratigraphic merging, stratigraphic splitting, and stratigraphic numbering.

[0029] Stratigraphic division, select the stratigraphic division in the engineering data, compare the field indicators and indoor indicators according to TB 10102-2023 Railway Engineering Geotechnical Test Procedure, and conduct stratigraphic division. This project is mainly implemented through an interactive window. Users can intuitively input and modify stratigraphic data and view the results of stratigraphic division in real time. Specifically, users can interact with the bottom depth value at the bottom depth position, or set the bottom depth on the actual bottom depth line.

[0030] Strata merging, select the stratigraphic merging in the engineering data, select the stratigraphic merging to be merged according to the instructions, and select the stratigraphic merging to be finally merged. It should be noted that after the merging is completed, the stratigraphic data of the borehole will be modified synchronously in the 2D survey software. In this process, rollback and redo are supported.

[0031] Stratigraphic splitting: select the stratigraphic splitting in the engineering data and select the stratigraphic splitting that needs to be split. Stratigraphic splitting only splits the same layer as before the split. After the splitting is completed, the stratigraphic data of the borehole will be modified synchronously in the 2D survey software, and rollback and redo are supported.

[0032] The stratigraphic number includes two situations: existing stratigraphic numbers and no stratigraphic numbers. The existing stratigraphic numbers are usually processed by modifying the stratigraphic numbers, while the non-stratigraphic numbers are processed by assigning unified stratigraphic numbers.

[0033] Existing stratum numbers are usually processed by modifying the stratum numbers. Specifically, select the unified stratum number in the exploration database editor, automatically count the strata of all exploration points, sort them from shallow to deep according to the depth of the stratum bottom, and stratify them according to the properties of the rock and soil layers. The properties of the rock and soil layers include rock and soil name, rock and soil type name, rock and soil age, rock and soil genesis, rock and soil density, rock and soil plasticity, and rock and soil weathering degree. If a layer already has a number, it will be displayed according to the existing number; if a layer has a layer number in the engineering standard stratum, it will be displayed according to the standard stratum number. You can also click to decompose the stratum number to the exploration point, and the stratum number will be automatically added to the stratum table of each exploration point, such as Figure 5 shown.

[0034] For those without stratum numbers, a unified stratum numbering method is used. Specifically, start the 3D layer connection tool and follow the prompt for stratum number design. If you select Yes, design the number first and then connect the layers. If you select No, do not design the stratum number and continue editing the borehole stratum and connect the layers manually. After completing the survey database editing, click on the survey database edit to perform stratum numbering.

[0035] According to the stratification situation revealed by the survey database and virtual drilling, the corresponding drilling stratification points of each stratum in the target blank section are connected, including automatic connection and manual connection.

[0036] Among them, automatic layer connection includes automatic layer connection of all sections and automatic layer connection of a single section. Automatic layer connection of all sections is achieved by clicking on the automatic layer connection of all sections, and the strata at the intersection of the sections are calculated and automatically connected according to the characteristics of all sections. The connection results are shown as follows: Figure 6 As shown, it should be noted that automatic layer connection supports rollback and redo.

[0037] The operation of automatic layer connection of a single section is to open the section that needs to be layered, click automatic layer connection, and when a single section is automatically layered, other sections will not be affected, and rollback and redo are supported, such as Figure 7 shown.

[0038] Manual layer connection: select the layer connection in the 2D section editing, and connect them through the layer connection line tool. Manual layer connection supports rollback and redo. The layer connection line tool supports drawing connecting layers, drawing pinch-out lines, and drawing fault lines.

[0039] In addition to the ability to connect layers in the survey database, the two-dimensional drawings drawn by geologists can also be imported as data sources. The cross-sections, longitudinal sections, and plan views of the work sites can be imported into three-dimensional space, and the cross-section views and geological boundaries can be integrated and displayed in the same space.

[0040] After the layer connection results are generated, they will be checked, including computer check and manual check. Computer check: After the computer layer connection or two-dimensional drawing import is completed, click the modeling data check in the data management to automatically check the layer connection results and display the error information in the directory tree, so that the data errors can be quickly located and modified. After the modification, check again until the inspection passes and the numbering is performed.

[0041] Manual inspection: By browsing the intersection of layer lines in three-dimensional space, check whether the boundaries of the geological body are unified. If not, modify the layer lines and nodes immediately, and modify the address boundaries of the end faces in the three-dimensional view. The modification process is reflected in the two-dimensional view of the corresponding face.

[0042] It should be noted that the changes made by the user in the 3D view will be updated in real time to the survey database and thus reflected in the 2D view. The changes made in the 2D view will also be mapped to the 3D display results.

[0043] After computer inspection or manual inspection, click Save Layer Line to save the layer connection results to the survey database. The layer lines entered into the survey database can be used directly when generating profiles in the 2D survey CAD.
