【摘要】:以長江中游典型放寬型淺灘礙航水道—牯牛沙水道為背景,根據(jù)實測資料分析了三峽水庫對牯牛沙水道水文泥沙特性的影響,研究了牯牛沙邊灘寬度及面積與汛后退水期天數(shù)的關(guān)系。在深入分析牯牛沙水道礙航特性的基礎(chǔ)上制定了航道整治方案,采用二維水沙數(shù)學(xué)模型對牯牛沙水道治理前后的汛后蓄水沖刷過程進行了模擬,分析了整體方案實施后的工程效果。
[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.
