关于水库汛期排沙控制水位的论证研究——以新疆玉龙喀什水库为例

Demonstration research on sediment control water level of reservoirs with serious sediment problems during flood season—Take Xinjiang Yulong Kashi Reservoir as an example

新疆大部分河流为季节性河流,大水大沙时期多集中在汛期,对泥沙问题较为严重的水库,汛期排沙控制水位的确定将直接关系到水库的淤损率。本文结合实际工程——玉龙喀什水库对汛期排沙控制水位进行论证研究,通过对比分析,最终提出一套既考虑汛期降低水位排沙,同时兼顾兴利的较优的汛期排沙控制水位,为水库规模设计提供可靠技术支持。

Most rivers in Xinjiang are seasonal rivers,and most of the heavy water and heavy sand periods are concentrated in the flood season.For reservoirs with serious sediment problems,the determination of the level of sediment control during the flood season will be directly related to the siltation rate of the reservoir.This paper combines the actual project—Yulong Kashi Reservoir to conduct a demonstration study on the control of water level for sediment discharge during the flood season.Through a comparative analysis,a set of better water control for sediment discharge during the flood season,which takes into account the reduction of water level during the flood season,and also takes into account Xingli,Reservoir scale design provides reliable technical support.
