本文采用有限元法,研究了拱坝坝肩稳定问题。着重探讨了断续节理岩体的非线性分析方法、根据凝聚力和摩擦力强度储备系数的最不利组合推求坝肩整体安全度等问题,获得了较为满意的结果。
In this paper, finite element method is used to study the abutment stability of arch dam. This paper focuses on the nonlinear analysis method of discontinuous jointed rock mass. According to the most unfavorable combination of cohesion force and frictional strength reserve coefficient, the overall safety of the abutment is deduced and the satisfactory results are obtained.
