Abstract: To establish the models for anisotropic geological body more precisely and display its preferred orientation of spatial distribution more explicitly, based on analysis of related software, this paper proposes a new 3D modeling method for anisotropic geological body by using Kriging Interpolation and Discrete Smooth Interpolation (DSI). The steps of the method include: data collection and sorting, Kriging Interpolation allowing for anisotropic distribution of these data, error analysis, and 3D modeling with DSI. This modeling method was applied to the study on weak layer ④ in a land newly reclamation zone of east Shanghai, showing the preferred orientation of spatial distribution of the weak layer ④ more directly, which provides reference and evidence of higher reliability for the projects such as foundation treatment, surface settlement prevention and treatment in the area.
