摘　　要：向家坝水电站泄洪消能具有高水头、大单宽的特点,泄洪时可能存在一定的雾化现象,而其下游紧邻居民生活区和大型企业生产区,对环境湿度要求严格。向家坝水电站结合自身泄洪消能特点,采用了高低坎双层多股淹没射流的新型消能工,成功解决了雾化对下游环境湿度的影响。介绍了向家坝水电站泄洪消能建筑物的体形,并根据向家坝水电站泄洪原型观测资料和水富县城气象站环境湿度监测成果,分析了其泄洪雾化范围及对水富县城湿度的影响,结果表明向家坝水电站泄洪未改变下游环境湿度。The energy dissipation of Xiangjiaba Hydropower Station is characterized by high head and large unit discharge,its atomization of flood discharge affects downstream residential areas and large enterprise production areas which require strict environmental humidity.Based on the characteristics of flood discharge and energy dissipation,a new energy dissipator with multi-horizontal submerged jet is adopted in Xiangjiaba Hydropower Station,which successfully solves the influence of atomization on downstream environmental humidity.The shape of the flood discharge and energy dissipation structure of Xiangjiaba Hydropower Station is introduced.According to the flood discharge prototype observation data of station and the environmental humidity monitoring results of Shuifu County Meteorological Station,the flood discharge atomization range and the influence on the humidity of Shuifu County are analyzed.The results show that the flood discharge of Xiangjiaba Hydropower Station has not changed downstream environmental humidity.
