摘　　要：攻关课题主要研讨小湾水电站拱坝泄洪消能布置。通过量测分析衬护水垫塘底板的时均动水压力和冲击压力、水流脉动压力、电站尾水波动等来优选坝身泄水孔口的体形和布置 ,同时注意避免水垫塘内形成强回流而产生低压区和挑流水股搭接、入水角太大所导致的水垫塘底板冲击压力过大等问题。体形布置优化后 。This paper discusses the arrangement of flood releasing and energy dissipation of the arch dam of Xiaowan Hydropower Station. Based on the measurement and analysis of the dynamic water pressure, impact pressure, flow pulse pressure and tailwater fluctuation of bottom slab of water cushion pool, the shape and layout of outlet opening of dam body has been optimally selected. Meanwhile it is important to avoid the occurrence of strong back flow and low pressure zone in water cushion pool and the big impact pressure on the bottom slab of water cushion pool. After the completion of optimal layout of body shape, the results showed that all indexes can meet the requirements of design.
