在梯级水库群中,关于大型控制枢纽设计洪水典型的选用,是一个比较复杂的问题,不象一般单独的枢纽那样简单。它涉及到各种洪水组合遭遇和上游干支流梯级水库群对洪水的调节作用;也涉及到控制枢纽及梯级枢纽的洪水如何调度等问题。由于洪水典型选用的不同,所求得的防洪库容,亦有较大的差异,这就会影响到水利资源的综合利用,也可能影响到大壩的安全,特别是大型控制枢纽都是一些共产主义的建设工程,关系国家千年大计,故在选用时,必须运用唯物辩证法则,特别慎重研究。长江三峡和汉江丹江口枢纽均为该河流最下一级控制枢纽,它的上游干支流建有梯级水库,对下
In cascade reservoirs, the typical design flood for large control hubs is a complex issue that is not as simple as a separate hub. It involves various flood combinations encountered and upstream dry tributaries reservoirs on the adjustment of flood regulation; also involves the control hub and cascade flood control how to schedule and so on. Due to the typical selection of floods, the flood control capacity obtained is also greatly different, which will affect the comprehensive utilization of water resources, may also affect the dam safety, especially large control hubs are some of the communal The construction project of doctrine, which is related to the national millennium plan, must be studied with materialistic dialectics in its selection. The Three Gorges of the Yangtze River and the Hanjiang River Danjiangkou hub are the lowest level of the river control hub, its upstream and downstream tributaries built cascade reservoirs, the next
