针对目前克孜尔水库存在的泥沙淤积问题,通过物理模型试验,研究了导流堤与排沙渠结合技术在克孜尔水库排沙中的应用。在平滩流量下,运用导流堤与排沙渠结合技术能较快地形成主槽冲沙,主槽形成后能有效地排除上游的泥沙。导流堤与排沙渠结合技术在水库排沙清淤中是可行的,且可与其他库排沙清淤措施联合使用,能较快地恢复水库库容,为那些对库型、用水与经济有一定限制的水库提供了另一种排沙清淤思路。
In view of the sediment deposition problem in Kezier Reservoir,the application of the combined technology of diversion dike and sediment desilting channel in the sediment desilting of the reservoir is studied here through physical model tests.Under general flow,by using the combined technology,the main sediment scouring channel could be faster formed,through which the upstream sediment could be desilted effectively.So this combined technology is feasible in the sediment desilting of reservoir,at the same time,it could be used with other sediment desilting measures to recover reservoir storage faster.This combined technology could also provide another new idea for the sediment desilting of the reservoir in water and economy restriction.
