Abstract:In order to pursue three-dimensional limit equilibrium analysis methods to widely practical applications,an interactive visualization system software SLOPE3D for slope stability analysis has been developed. It contains the pre-processor,the limit equilibrium analysis solver and the post-processor. In the pre-processor,the construction of three-dimensional geological model of the slope structure provides geoinformation presentation for the limit equilibrium solver. In the post-processor,the effective three-dimensional visualization of data sets can assist the user with interpretation and analysis of the calculation results. The SLOPE3D system combines 3D visualization of geoinformation in slope engineering with limit equilibrium analysis for slope stability. Because of its user-friendly interface and 3D graphics capabilities with high quality,the geotechnical engineers can easily apply SLOPE3D to practical engineering problems.
