| Abstract: | Combining with FEM method,the deposit slope stability analysis under earthquake action is performed with the response spectrum method.Through a practical project,the variation of slope stress and displacement is analyzed,and the method for calculating the slope safety factor is given.The comparison of the calculated result with that obtained by the pseudo-static analysis method shows that the present method is reasonable.Furthermore,the scope of future application of the response spectrum method in deposit slope analysis is also discussed. |
