| Abstract: | Through the research into 10 groups of field direct shear tests on the gneiss rock mass on the damsite area at Xiaowan High Arch Dam, the mechanic parameters of the foundation rock have been obtained. The new method which can predict rock mass shear strength is put forward and the shear failure mechanism is also analysed by theory of fracture mechanics. The parameters have been accepted in the preliminary design phase of Xiaowan Arch Dam. |
