Long and large strip-shaped three-dimensional geological environment modeling method and device and terminal device

Abstract

The invention is suitable for the technical field of geological modeling, and provides a long and large strip-shaped three-dimensional geological environment modeling method and device and a terminaldevice. The method comprises the steps of obtaining the topographic information and the geological information required for modeling a preset area; partitioning the preset area according to a preset interval, and obtaining the strip-shaped boundary range feature line data of each partitioned area according to a partitioning result and the topographic information; modeling each block area accordingto the obtained strip-shaped boundary range characteristic line data, the topographic information and the geological information; obtaining the spatial positioning points of the geological solid model of each block area after modeling according to a preset interval; connecting the geologic entity models of the block regions according to the spatial positioning points and the common strip-shaped boundary range characteristic line data of the block regions; and obtaining a long and large strip-shaped three-dimensional geological environment model. According to the present invention, the geologic body in the long and large strip-shaped geological environment can be better constructed and displayed, and the method, the device and the terminal device are more suitable for the long and large strip-shaped railway line selection engineering.

Description

technical field [0001] The invention belongs to the technical field of geological modeling, and in particular relates to a modeling method, device and terminal equipment of a long strip-shaped three-dimensional geological environment. Background technique [0002] In the process of railway line selection, terrain and geological environment are the key factors that directly affect the direction of the line, and line selection on the traditional 2.5-dimensional contour line cannot give a good intuitive feeling of the terrain and geological environment, especially For unfavorable geological areas, it needs to be analyzed through traditional engineering geological survey reports, topographic maps, engineering drilling columnar diagrams, and drilling section diagrams of some routes. As far as railway engineering is concerned, it can no longer meet the requirements of railway design for high-speed construction in my country. [0003] Applying 3D geological environment modeling to t...
