| 摘 要： | 采用水深平均有限元法平面二维数学模型,根据伽辽金加权余量法离散模型方程组,并结合Newton-Raphson迭代法,较好地模拟了江津仁沱地区河道水流流场。经綦江仁沱河段的实测水面线、水流流速分布验证,其计算结果令人满意。

| Abstract: | The planar 2-D mathematical model is established by depth-averaged finite element method.The current field of Rentuo District in Jiangjin is preferably simulated by Galerkin method of weighted residuals that disperse the equations and Newton-Raphson non-linear iteration.The result proves to be reliable and satisfying through the verification of actual surface-line and velocity of flow of Rentuo reach in Qijiang. |
