【摘要】：以长江中游典型放宽型浅滩碍航水道—牯牛沙水道为背景,根据实测资料分析了三峡水库对牯牛沙水道水文泥沙特性的影响,研究了牯牛沙边滩宽度及面积与汛后退水期天数的关系。在深入分析牯牛沙水道碍航特性的基础上制定了航道整治方案,采用二维水沙数学模型对牯牛沙水道治理前后的汛后蓄水冲刷过程进行了模拟,分析了整体方案实施后的工程效果。
[Abstract]:Based on the background of Guluisha waterway, a typical broadened shoal channel in the middle reaches of the Yangtze River, the influence of the three Gorges Reservoir on the hydrological and sediment characteristics of Gulusha waterway is analyzed according to the measured data, and the relationship between the width and area of Guniusa beach and the number of days after flood recessions is studied. Based on the in-depth analysis of the navigation hindrance characteristics of Gulusha waterway, the waterway regulation scheme is worked out. The two-dimensional water and sediment mathematical model is used to simulate the process of water storage and scour after flood season before and after the treatment of Gulusha waterway, and the engineering effect after the implementation of the whole scheme is analyzed.
