Abstract: | 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. |
