摘要
从平面二维水动力学方程组出发,根据有限元Galerkin加权余量法离散模型方程组,并利用Newton-Raph-son迭代法求解,成功地模拟了重庆双碑嘉陵江大桥桥区河道水流流场.经综合分析,得出大桥的建设对通航水流的影响很小.
Based on the difference equations for 2-D depth-averaged water flow and solved by the finite element method using the Galerkin method of weighted residuals and Newton-Raphson non-linear iteration,the flow field at the bridge area of the Shuangbei Jialingjiang Bridge is successfully simulated in this paper.A comprehensive analysis demonstrates that the influence of the project construction on the navigation flow conditions of the river is very small.
