三峡船闸下游口门区流态及其改善措施的研究

本文依据三峡船闸下游口门区水流条件的模型试验结果,分析了口门区的水流特性,回流机理以及影响回流强度的各种因素,并提出改善口门区水流条件的有效措施。结合水流和船模试验结果,还对有关通航标准进行了探讨。

Study on the Flow regime at the Downstrem Entrance Area of the Three Gorge Lock and its Improving Measures

In this paper , based on the model test results of the flow conditions at the downstream entrance area of the Three Gorge Lock , the systematical analysis is given to the flowage and the backflow mechanism at the entrance area and various factors that influence the backflow intensity . The effective measures to improve the flow conditions at the entrance area are also proposed. Furthermore, according to the test results of the flow and ship model,the navigation standard i s discussed.
