摘　　要：混凝土重力坝作为挡水建筑物,已广泛应用于水利水电工程中,但对于体型单薄的混凝土重力坝,在运行过程中,特别是地震荷载作用下,容易出现应力集中和滑动失稳现象。该文依托石城子二级电站工程,采用有限元数值模拟方法,对其压力前池末端的单薄混凝土重力坝开展静动力特性研究,并基于有限元分析成果研究重力坝的抗滑稳定性。该研究成果对类似单薄混凝土重力坝工程具有参考价值。As a water retaining structure,concrete gravity dam has been widely used in water conservancy and hydropower projects,but for thin concrete gravity dam,stress concentration and sliding instability are easy to occur in the process of operation,especially under seismic load.In this paper,based on the Shichengzi secondary power station project,the static and dynamic characteristics of the thin concrete gravity dam at the end of the pressure fore pool are studied by using the finite element numerical simulation method,and the anti-sliding stability of the gravity dam is studied based on the results of finite element analysis.The research results are of reference value to similar thin concrete gravity dam projects.
