三峡为中心的长江防洪系统优化调度网络分析法

Network analysis method used in Changjiang flood prevention system optimal operation centered in the Three Gorges

本文主要研究三峡工程与上游有防洪作用的一些水库、中游的堤防、分蓄洪区、支流水库共同组成的复杂防洪系统的优化调度．针对复杂庞大的长江防洪系统用网络模型进行求解，主要成果是建立了长江防洪系统的时空网络模型，及提出了将宜昌至汉口洪水演算模型与网络模型柔合在一起的求解方法，该法扩展了网络模型的应用领域．

Network analysis method is used to investigate the optimal operation of the complicated flood prevention system composed of reservoirs in upstream,dikes and flood retain area in middle reaches as well as reservoirs in branch rivers.The results are as follows:1 Changjiang flood prevention system time space network model is presented,2 the respective method in which network model is combined with flood routing model from Yichang to Hankou is discussed.The applications show that the network model is reasonable and practicable.
