Stability analysis of completely-strongly weathered high-steep rock slope
Based on a case of completely-strongly weathered high-steep rock slope in Chengmenshan Copper Mine, the mechanical parameters of the decomposed rock mass are determined by strength reduction calculation with Hoek-Brown nonlinear failure criterion as well as data processing method, in line with field investigation of engineering and hydrological geological condition. The excavation of slope is simulated step by step with FLAC3D and the corresponding failure mechanism is analyzed and the potential landside mode is decided. The results show that the whole slope is stable but several benches of slope will lose their stability. Besides, a reinforcing resolution is proposed here.
