Application of GMTM for the Analysis of Foundation Pit Engineering

Considering the advantage that 3D geologic model can better reflect the actual geological conditions, a new and practical modeling method (Geologic Model Transforming Method) was presented. The new modeling thought was that the initial surface model formed with geologic model was transformed into the numerical model. In this method, the key techniques of region cutting, surface model reconstruction and auto-meshing were used. All procedures were carried out rapidly by programming. An example of foundation excavation was given to illustrate the application of the method. The implementation of the method resulted in high efficiency and automaticity of modeling. The proposed technology will give some useful references to the continuous researches on this subject.
