Abstract

The invention discloses a large complex three-dimensional geologic model grid coarsening method based on a BIM technology. The large complex three-dimensional geologic model grid coarsening method comprises the steps: S1, preliminarily establishing a three-dimensional geologic model based on BIM software, and solving a geologic interface intersection line; S2, regenerating and coarsening the preliminarily established geological grid through a geological interface; S3, importing the regenerated geological grid into ANSYS to generate a geological body grid; and S4, importing the geologic body grid generated in the ANSYS into FLAC3D to carry out numerical simulation analysis. The large complex three-dimensional geologic model grid coarsening method achieves technical breakthrough, is clear inexpression, is convenient to use, is suitable for CAD / CAE integration of large complex three-dimensional geological models, is clear in the thought, and is easy and convenient for operation.

Description

technical field [0001] The invention relates to three-dimensional numerical simulation calculations in related fields of water conservancy and hydropower engineering, in particular, it is a BIM technology-based grid coarsening method for large and complex three-dimensional geological models. Background technique [0002] At present, with the continuous promotion of BIM technology, a 3D geological modeling system completely oriented to water conservancy and hydropower engineering geology has emerged. The 3D geological model created by this type of system can fully express and display the geological conditions of the hub project area. Due to the complexity of the model and the incompatibility of the data structure, it is impossible to directly convert it into a CAE calculation model, especially the number of 3D geological model grids built is as many as hundreds of thousands or even millions. , coarsening the geological grid is an indispensable prerequisite work.
