Application of Strength Reduction FEM in Anti-sliding Stability at Dam Foundation

An analysis on safety factor of anti-sliding stability at dam foundation through c-phi reduction algorithm by finite elements is presented. When the system reaches instability, the numerical non-convergence occurs simultaneously. The safety factor is then obtained by c-phi reduction algorithm. Complex rock foundation of Xi He power station has been analyzed by using strength reduction FEM and the safety factor of anti-sliding stability at dam foundation has been obtained. The result shows this method is feasible.
