FLAC3D Modeling of Complex Geologic Body Based on Kriging and Reverse Engineering and Its Application

The numerical simulation of complex geologic body is one of the difficulties in geotechnical engineering. The improved Kriging interpolation method and reverse engineering technology were depended to propose such a new 3D modeling method for complex geologic body that Kriging interpolation was used with the advantages of reverse engineering to get the surface model of geologic body fast, and then establish the 3D model of complex geologic body accurately and rapidly by loading into FLAC3D software with the file programmed by Fish language. The modeling method was applied to the 3D field simulation of a project and, with the comparison with the theoretical calculation, its feasibility and validity was verified. Simultaneously, 3D simulation may provide the comparison of the deformation at different sections from different angles.
