摘　　要：在有限元理论基础上,借助ANSYS平台结合强度储备安全系数法的实施步骤,可以很好地模拟混凝土拱坝工程中的抗滑稳定问题,通过算例的计算表明其相应的安全系数与理论值基本吻合.该方法用于拱坝的抗滑稳定分析,不仅得到坝肩的稳定安全系数还可以对断层滑裂面进行相关的求解.Based on the finite element theory,the anti-sliding stability in the concrete arch dam project can be well simulated by combing the implementation steps of reserve safety factor method with ANSYS platform.An example of calculation shows that the corresponding safety factor is consistent with the theoretical value.An analysis of the anti-sliding stability of arch dam with this method can not only obtain the safety factor of the abutment stability,but also solve the problem of fault slip surface.
