摘要
Concrete gravity dam has been selected for Xihe Hydropower Station, and it has high demand for shear strength of rock mass in the foundation. Through exploration, many low-angle dip structural planes have been found at the dam site. Because low-angle dip structural plane is the key factor to affect the anti-sliding stability of foundation, it is necessary to evaluate the anti-sliding stability of dam foundation. Firstly, study on the distribution regularity and joint persistence ratio of low-angle dip structural planes at the dam site would be carried out. Then reasonable shear strength parameters of rock mass in the dam foundation could be suggested through comprehensive analysis.
