Problems solved by technology

This method is suitable for modeling geological bodies at large scales, but the modeling precision and accuracy are not high at small scales;
[0005] The second type is based on section data modeling, that is, using drilling, geophysical prospecting and other data and expert knowledge to arrange and draw sections, and then using the sections to build geological body models. The accuracy of the model depends on the number of arranged sections, and this method cannot be used well. Geological data other than section lines, and the modeling workload is relatively large

Embodiment Construction

[0026] In order to better illustrate the present invention, further description will now be made in conjunction with the embodiments and accompanying drawings.

[0027] Such as Figures 1 to 5 As shown, based on the geological disaster underground stratum plane analysis method, the method includes the following steps:

[0028] (1) Use ArcGIS desktop software to make the exploration drilling record point layer into a shapefile point format file supporting (x, y, z) three coordinate axes, (x, y) is used to represent the two-dimensional ground plane The longitude and latitude coordinate position, the z-axis represents the altitude based on the earth reference sea level;

Abstract

The invention discloses an underground rock stratum plane analysis method based on geological disasters. The method comprises the following steps of S1, making a file in a shape file format; S2, importing data; and S3, performing spatial analysis operation. The method is advantaged in that manual drawing is not needed, and automatic analysis is completely achieved; a user can simply draw a polygonal range at any position to obtain a desired karst plane three-dimensional image conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of electronic geographic information processing, in particular to a plane analysis method for underground rock formations based on geological disasters. Background technique [0002] Geological body modeling is of great significance for understanding subsurface lithology and geological characteristics. Due to the large scope of regional geological body modeling and the huge and complex data, it is more complicated to establish a geological body model. [0003] At present, the analysis of subsurface strata sections of geological disasters can be divided into two categories according to the data source: [0004] The first type is modeling based on borehole data, that is, directly import borehole-related data into modeling tools to automatically generate geological body models. This method is suitable for modeling geological bodies at a large scale. When it is at a small scale, the modeling precision and accu...
