Stability analysis and three-dimensional visual simulation system of landslide at reservoir banks

Based on the limit equilibrium analysis method of slope stability, three-dimensional(3D) digital slope modeling technique and visual dynamic simulation technique, the VisualSlope system of slope stability analysis and 3D visual simulation at reservoir banks is developed by the VC++ tool. The implementation procedure includes three stages of the system analysis, the system design, and the system development. The VisualSlope system reads all geometric parameter data through the graphic object library and the database. Then, a series of subsequent tasks can be accomplished, such as stability computation, visual analysis of computational results, instability 3-D dynamic simulation and demonstration analysis. The developed system consists of abundant computational and analytical functions, with preferable generality and strong practicability. It can offer a technical support platform to slope stability analysis and control in reservoir banks.
