Application of three dimensional geological models to geotechnical engineering problems

摘要

Sophisticated understanding of the subsurface geology is prerequisite for solving engineering geological and geotechnical problems. Since the 1980s, advanced computer and information techniques have led to the possibility of generation of highly precise three dimensional (3D) geological models. Compared with traditional 2D maps, 3D models can not only provide engineers and designers with complete and intuitive visualization of subsurface condition, but rather are capable of storing diverse information. In this paper, we introduced the modeling procedures by virtue of two case studies, which are subsurface modeling for the urban area and surface modeling for a quarry slope. Three typical applications in the field of geotechnical engineering, i.e. civil engineering constructions, slope stability analysis and numerical analysis, are illustrated by the two models.
