引桥式高桩码头对弯道河流流态影响的数值模拟

Numerical Simulation Research on the Bend River Flow Form of Pile Wharfs with the Approach Bridge

为研究引桥式高桩码头对弯道河流流场的影响,建立平面二维数学模型,基于弯道水流的运动机理,首先对数学模型进行了典型试验验证,然后模拟广东西江一引桥式高桩码头对该河弯道段流场的影响,指出码头建设使弯道河道流速发生了独特变化,关于此方面的数值计算有待进一步研究.

To study the affection by the pile wharfs with approach bridge, the plane 2-D mathematical model is built up. Based on the motion mechanism of the bend flow, first, the mathematic model is tested by the representative experimentation, then the affection of a pile wharfs with approach bridge on the bend reach of Xijiang river of Guangdong is simulated,that the especial changes of bend flow by the pile wharfs is pointed out, and the deficiency in the numerical calculation need further research.
