Safety Estimation of Deep Sliding Stability of No.3 Dam Foundation of Left Powerhouse of Three Georges Project Based on 3D FEM

摘要

3D-FEM computation model included in the real attitude and distribution of large structures and faults in the No.3 dam foundation of Three Georges Project is created. The deep sliding stability of above dam foundations has been studied. A rational and applied evaluative method of safety factor of dam foundation is presented. The safety factor of sliding stability based on the concept of strength repertory of No.3 dam foundation is given.
