摘　　要：龙滩水电站大坝为高碾压混凝土重力坝,最大坝高216.5m,分两期建设,前期坝高192m。其抗震安全性研究主要采用材料力学动力法和有限元动力法进行,同时也采用非线性有限元动力分析。研究结果表明,龙滩大坝具有较好的抗震安全性及一定的超载能力。The Longtan hydropower station includes a high RCC gravity dam with a height of 216.5 meters. It will be constructed by two stages. In the first stage a 192 m high dam will be built. The anti-seismic safety of the dam is analyzed using dynamic methods of materials mechanics and finite elements, non-linear finite elements ones as well. The results showed that its anti-seismic safety was comparatively good and to some extent it could be overloaded.
