BIM-based three-dimensional geological automatic modeling method

Abstract

The invention relates to the field of BIM automatic modeling, and especially relates to a BIM-based three-dimensional geological automatic modeling method. The method is characterized in that the method at least comprises the following steps: acquiring prospecting data, i.e., introducing a prospecting geological or boring data source file into a geological database; and scheduling the geological database and performing modeling, i.e., a Revit platform obtaining the prospecting geological or boring data source file I from the geological database and performing modeling according to the source file. The method provided by the invention has the following advantages: a three-dimensional geological model is constructed and generated automatically and rapidly out of the prospecting data, the process includes entity construction, material rendering, attribute modeling and the like, users are enabled to browse from a three-dimensional angle and manage prospecting accomplishments, and the effect of BIM demonstrated in the field of engineering prospecting is further tapped.

Description

technical field [0001] The invention relates to the field of BIM automatic modeling, in particular to a BIM-based three-dimensional geological automatic modeling method. Background technique [0002] With the deepening application of BIM in construction engineering, especially geotechnical engineering, more and more customers need to model the formation. In the process of 3D visualization of geotechnical engineering survey and geological results, direct use of Revit software for manual modeling has certain limitations, as follows: [0003] 1) Manual input of drilling data and manual modeling of rock and soil layers, the modeling workload is heavy and cumbersome, error-prone, and modeling efficiency is low; [0004] 2) When building a 3D geological model, it can only deal with conventional rock and soil strata, and it is difficult to deal with common phenomena such as lens and pinch-out rock and soil strata, and only rough modeling of rock and soil strata can be performed; ...
