| description | Aiming at the large range and depth of toppling and cracked deformation occurred in a typical toppling slope during the excavation in Miaowei hydropower station on the Lancang River, through geological survey, the classification standard system for toppling deformation rock has been established based on the main characteristic indexes of rock mass, and the mechanism of the toppling and tensile deformation of the slope at Miaowei is revealed. Comprehensive rescue reinforcement measures were implemented to control the development of deformation and to maintained the stability of the slope, which included prestressed anchorage and systematic drainage. Numerical simulation was implemented to predict the deformation and guide the reinforcement. The numerical and monitoring results both show that the deformation has been effectively controlled and the slope is already in a stable state with the completion of reinforcement measures. The study on the deformation mechanism and the successful practice of treatment of typical toppling slope in Miaowei hydropower station provide a constructive reference for similar complicated slopes. |
