Three-dimensional geological rapid modeling method for long and large strip-shaped linear engineering

Abstract

The invention relates to a three-dimensional geological rapid modeling method for long and large strip-shaped linear engineering. The method comprises the following steps of acquiring basic data; dividing a modeling unit; drawing an exploration profile sketch; modeling a wireframe model; modeling a geological interface; geologic body modeling; modeling a special geologic body; geologic body post-treatment; three-dimensional geologic model assembly. According to the method, curve element data of line lines are deeply analyzed, so rapid and accurate partitioning of a geological modeling area isrealized; a shared profile is preset in advance to ensure the connection of stratums at joints of the geologic body blocks; for a geological body with a complex special structure, a flexible and rapidinteractive modeling mode is adopted, so that the modeling efficiency is greatly improved, and a problem that the geological body cannot be created manually is solved; a solution is provided for thecollaborative problem of geologic modeling carried out by multiple persons, large-scale geologic modeling work can be carried out according to the method, working efficiency is improved, and the modeling quality is guaranteed.
