摘　　要：采用反应谱法考虑地震作用的动力特性,使用有限元方法,分析地震作用下崩塌堆积体边坡的稳定性;结合具体的工程实例,分析按反应谱法考虑的有限元计算结果的应力、位移变化,给出了安全系数计算方法,并与拟静力法计算结果进行对比分析,表明本文方法较合理,从而探讨了反应谱法在崩塌堆积体边坡稳定性分析中的应用前景。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.
