摘　　要：金安桥水电站枢纽工程位于强震地区,大坝地震设防烈度为9度,地震动峰值加速度为0.3995g。碾压混凝土重力坝最大坝高160m,地质条件复杂,坝基分布有4层凝灰岩、河床坝基主要为裂面绿泥化岩体、节理裂隙发育。介绍了碾压混凝土重力坝设计及主要技术问题。The complex structures of Jinanqiao Hydropower Station are located in an area having high earthquake intensity. The estimated seismic intensity for the dam is of degree IX with seismic dynamic peak acceleration of 0.3995g. The RCC gravity dam has a maximum dam height of 160m. Geological conditions in this area are relatively complicated. The dam foundation distributes four-layer tuff. Riverbed foundation is mainly composed of crack chloritite with joints being well developed. The essay mainly introduces technical issues in design of RCC gravity dam.
