【摘要】 本文用三维非线性有限元法研究分析了采用刚体极限平衡分析复杂地基上拱坝坝肩稳定时,将坝肩岩体假定为刚体及假定滑裂面等的影响,其计算结果与实际有较大差异,用该法成果判断坝肩稳定安全系数一般偏于安全。更多还原

【Abstract】 The study of the influence of stalility analysis of an arch dam abutment owing to the rigid hypothesis of rock mass and the assumming sliding face and direction of rigid block equilibrium method are made in this paper by 3D nonlinear FEM.It finds that the safety factor of stability calculated by above method is always on the low side.更多还原
