以龙滩水电站大坝为例，对碾压混凝土高重力坝可靠度进行了系统分析，采用JC法、三维随机有限元法研究坝体坝基联合作用下的可能失效途径，得出大坝抗滑稳定最薄弱部位仍然在建基面上等若干有益的结论。
Taking Longtan Hydropower Station dam as an example, the reliability of RCC gravity dam is systematically analyzed. JC and 3D finite element method are used to study the possible failure paths under the joint action of dam foundation. Stabilization of the weakest parts of the foundation is still a number of useful conclusions.
