永庆水库是丰满水电站的反调节水库，枢纽布置时要考虑丰满水电站调峰运行时的下泄流量以及保持不间断地向下游供水等因素，泄水建筑物需具备挡水、供水和泄洪功能，布置比较复杂。文章着重介绍了枢纽布置方案的比选、泄水闸、自由溢流坝、混凝土重力坝及砂砾石坝的设计特点。 Yongqing Reservoir is Fengman hydropower station anti-regulation reservoir, the hub layout to consider Fengman hydropower peak load discharge and maintain uninterrupted downstream to the water supply and other factors, the building should be equipped with water retaining, water supply and spillway functions, The layout is more complicated. The paper focuses on the comparison of hub layout schemes, design features of sluice gates, free spillway dam, concrete gravity dam and gravel dam.
