高重力坝抗滑稳定安全度分析
Stability safety degree against sliding in high gravity dams
摘要
Abstract
In order to ensure the stability and safety of high gravity dams, the shear strength envelope curve in the shape of quadratic parabola was studied with regard to the nonlinear relationship between the shear strength and the normal stress for high dam foundations. On such a basis, a performance function based on the shear strength envelope curve in the shape of quadratic parabola was established. Combined with the improved JC method, a method for calculating the reliability of dam foundation failure was proposed, and the corresponding program was developed. The above basic principles and methods were applied to the calibration of safety degree for the stability of a high dam after rehabilitation. The results indicate that the dam has certain reserved capacity of stability safety after rehabilitation.关键词
