Safety Analysis of Plant Slope of Haokou Power Station

Abstract:

The Haokou power station is located in the south of Wu Long in chongqing, which is a medium-sized hydropower project given priority to electricity. The Dam located in south bank of Wujiang river downstream of Furong river has the catchment area of 7400 km², total capacity of 94.12 million m³, installed capacity of 125 MW power . After the excavation of the main building, trailing edge to form 30 m high rock slope is tangential. Slope rock mass is given priority to with weakly weathered shale, mudstone, shallow accumulation horizon, thickness is about 0.5 m to 6.0 m. In analysis of slope stability, the FLAC 3d and the strength subtraction method was used. Considering of gravity, the shore web of pressure, water pressure and reinforcement bolt load combination, the stress response, displacement response, plastic zone as well as the safety factor of slope was analyzed. The calculation results show that the slope is stable.
