Description

Technical field [0001] The present invention relates to the field of BIM technology, in particular to a BIM-based method and system for interpretation of comprehensive geotechnical engineering survey information. Background technique [0002] At present, BIM technology has been widely used and promoted in many industries of engineering infrastructure construction. Various CAD software and three-dimensional modeling software have carried out many attempts in the fields of architecture, structure, highway and railway bridges, water conservancy facilities, and provided a variety of modeling methods. However, the current BIM applications are mostly BIM modeling applications for structures to be constructed, and there is a lack of systematic BIM modeling methods for existing geological bodies. The BIM applications for survey results focus on a single analysis of drilling or geophysical results, with different data formats , Information interaction is not smooth, and there is no three...
