Deep Anti-Sliding Stability of Wudu RCC Gravity Dam

Abstract:

The deep anti-sliding stability of dam foundation has been an important issue in the study of dam field. Rigid body limit equilibrium method and nonlinear finite element method have been adopted on the analysis of sliding stability. In the current paper, the joint element is used to simulate faults, interlayer shear zone and slight inclined fissure zone in complicated geological conditions of Wudu dam. Stress integral method, overload method and strength reduction method are utilized for analysis on deep anti-sliding of Wudu RCC gravity dam, moreover, after being compared with the results by Sarma method, finite element direct force method and geomechanical model test method etc., the consistent conclusion is obtained.
