摘要
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 。
There exists a vacillated riverbed, about 2km wide, around the Najin hydroelectic station on the Lasa river. Based on velocity field analysis and model test, an optimal scheme was chosen for the setting of silt releasing sluice. Consequently, the back flow in the reservoir of the hydropower station was eliminated. Thus, the extent of the sediment deposition is greatly mitigated, and the flood control capacity of the reservoir is enhanced.
