AI Technical Summary

Problems solved by technology

3D geological modeling can intuitively express the spatial shape and characteristics of geological bodies, perform real 3D spatial operations and analysis, and greatly promote the scientific management and sharing of geological information. With the development of computer technology and 3D geological modeling With the maturity of technology, many relatively mature commercial software have been developed abroad. However, most of the existing commercial 3D geological modeling tools are for 3D geological modeling of a certain site, and the interactive workload is large, which is difficult to meet the requirements of fast and efficient linear engineering. In terms of actual engineering application, there are mainly the following constraints:

[0004] (2) Modeling quality problems

[0005] (3) Difficult modeling of special geological bodies

Special geological bodies such as lenses, cave groups, landslides and collapses, due to the complexity and uncertainty of their spatial form, it is difficult to complete the modeling with simple operations such as translation and rotation, and the modeling work of special geological bodies seriously restricts geological modeling efficiency
