京密引水渠作为向北京市输送水源的大动脉,如何减少渠道的水量损失,节约有限的水资源,成为京密引水管理处在供水工作中需要解决的迫在眉睫的问题。在水资源日益紧张的情况下,对京密引水渠冬季输水调度方案进行调整是非常必要的。通过对近几年京密引水渠冬季输水方案和渠道运行情况及渗漏数据进行的分析说明,采用调整后的冬输低水位运用方式可以明显减少渠道渗漏,从而减少从密云水库的引水量,同时渠道没有明显的冻胀破坏。
As a major artery that supplies water to Beijing, the Jingmi Drainage Channel can reduce the amount of water loss in the channel and save a limited amount of water resources. This has become a pressing issue to be solved in the water supply of the Jingmi Diversion Project. Under the condition of increasingly tense water resources, it is necessary to adjust the winter water transfer schedule of Jingmi diversion canal. Through the analysis of the winter water conveyance scheme and canal operation data and leakage data of Beijing-Beijing diversion canal in recent years, it can be concluded that using the adjusted mode of winter low water level transmission can obviously reduce canal leakage and thus reduce the lead from Miyun Reservoir Water, at the same time there is no obvious channel of frost heaving damage.
