高坝瞬时泄洪对坝下游船舶航行及码头影响的数值模拟

Numerical simulation of ship sailing and harbor operation safety due to transient flood of hydropower dams

    摘要
  • 摘要: 以描述河流瞬变流的运动方程为基础,得出了模拟瞬时洪水波和溃坝波在天然河道和干河床中传播过程的数值计算方法.运用该方法模拟分析了金沙江向家坝突然泄洪过程,以及瞬变流对坝址下游165km长河道中船舶航行和码头的影响.

     

    Abstract: Based on the kinematic equation describing transient flow in a river,a numerical calculation method is developed to simulate the propagating process of the transient flood wave and dam-break wave in a natural river and on dry river beds.By use of this method,the transient flood process of Xiangjiaba Hydropower Station in Jinshajiang River is simulated,and influences of the transient flow on ship sailing and harbor operation 165 km downstream of the dam are analyzed.
