向家坝转运码头港区通航水流条件数值模拟和分析

Numerical Simulation of Navigable Water Conditions at the Transshipment Terminal of Xiangjiaba

对向家坝水电站施工截流期上游二狮岩和新滩坝两个临时转运码头进行通航可行性论证,建立了二维水流数学模型,分析比较了码头工程建设前后港区水域条件变化情况。计算结果表明,工程建设对航道通航影响微弱,工程可行。

The feasibility study is carried out on the navigation of two temporary transshipment terminals called Ershiyan and Xintanba, which are used at the upstream of Xiangjiaba Hydropower Station in the closure construction period. Two-dimensional mathematical model of water flow is used to analyze and compare the changes of water condition before and after the construction of transshipment terminal. The result shows that the engineering construction has faint influence on navigation condition and the project is feasible.
