摘　　要：采用基于可靠度理论的分项系数有限元强度储备法,对亭子口水利工程进行平面非线性有限元坝基抗滑稳定分析.通过计算分析,得到坝基渐进破坏的过程,并揭示出坝基深层滑动模式.同时,采用常规强度储备系数法和刚体极限平衡法对坝基抗滑稳定进行核算,结果表明工程坝基的抗滑稳定是有保证的.The strength accumulation coefficient method based on partial coefficient of reliability theory is applied to Tingzikou hydropower project. According to the computation, the gradual destruction process is displayed; and possible sliding modes are set up. Meanwhile, conventional strength accumulation coefficient method and rigid body limit equilibrium method are adopted to verify the anti-sliding stability of the dams it is shown that the anti-sliding stability of the dam can be ensured.
