Abstract
锛?/p>
Anti-sliding stability analysis of gravity dam on complex foundation is a key point in
gravity dam design. Regular limited equilibrium method can
鈥檛 help to find the most dangerous failure
surface exactly and objectively. In this paper
锛?/p>
anti-sliding stability analysis of a gravity dam in
Zhejiang is simulated by FEM under three different conditions
锛?/p>
based on strength reduction method.
Results show that the calculating safety factors meet specification requirements. The study results
provide a reference for similar projects.
