| Abstract: | The back slope behind the powerhouse of Tianhuaban Hydropower Station is about 243 m high and the permanent excavation height is 85 m.The slope stability is analyzed based on the rock mass mechanical parameters for designing the support.According to the requirements of Specification,the sliding and wedge stabilities of excavated slope are calculated and the supports are also studied,and the reasonable excavated slope ratio and support parameters are finally selected. |
