利用异重流在极端天气下改善水库泥沙淤积问题研究

Research on using reservoir to improve reservoir sedimentation environment

为实现水库可持续利用,减少水库泥沙淤积,同时解决极端天气下我国水库城市供水问题,通过对异重流排沙与浑水水库排沙两种排沙方式进行比较分析,提出了异重流和浑水水库联合排沙的方式来导引入库浑水排出,同时缩短入库浑水滞库时间,并指出该方式在水库排沙实际运用中的几点建议。

In order to realize the sustainable utilization of reservoirs,reduce the siltation of reservoirs,and solve the problem of water supply for reservoirs in China during extreme weather,a comparative analysis of the two types of sand discharge methods:gravity flow sediment discharge and waste water discharge from the Tangshui Reservoir is proposed.The combination of gravity flow and the Yushui Reservoir combined with sand draining led to the introduction of muddy water discharge,while shortening the time for delaying storage of muddy water,and pointed out some suggestions for the practical application of this method to the reservoir.
