拉萨河纳金电站具有宽约 2 km的游荡型河床 ,通过流场分析及试验研究 ,优选出冲沙闸设置的最佳方案 ,从而消除了前池的大回流流态 ,减轻了泥沙淤积危害 ,提高了库区的防洪能力
The Lhasa River NPN has a wandering river bed with a width of about 2 km. By means of flow field analysis and experimental study, the optimal scheme of flushing sluice gates is optimized so as to eliminate the large backflow of the forebay and reduce the sediment deposition Endanger the flood control ability of reservoir area
