Abstract: In hydropower engineering, engineering slopes on both river sides have characteristics of large scale, high and steep geometry, long service life and high stabilization requirement. Due to real-time changes of geological parameters, slope structure and excavation support, real-time evaluation of slope safety is a key technical issue in hydropower projects. A real-time simulation method based on numerical method is developed by considering the change of excavation progress during slope construction process, the new geological information disclosure, the modification of supporting plans and the correction of numerical parameters. This procedure focuses on real-time analysis and control of the safety of high-steep slopes, which is seldom reported in the previous studies. Based on database technology and secondary development of ABAQUS software, the information of dynamic mapping the construction schedule, geology and support is implemented into the numerical model. Finally, a real-time analysis and control system for slope safety is developed to realize the simulation and forecast of the real-time slope safety status.

Key words: slope engineering, real-time numerical model, dynamic mapping method, slope system development
