摘　　要：运用沿平均水深平面二维浅水方程,采用贴体正交曲线坐标,建立水流数学模型,模拟了重庆寸滩三期工程河段水流条件并根据实测资料进行流速流向过程、流速分布的验证,计算结果表明,二维浅水方程能较好地模拟工程河段河道水流流场。Mathematical model is built for smulating rivers condition of The Phase Ⅲ Project of Chongqing Cuntan resch,it bases on orthogonal body-fitted coordinate and two-dimension shallow water equation. Verification calculation is performed about velocity and transverse distrihutes of velocity. Contrasted with the observed data, the result shows that it can accurately simulate the velocity field of project reach.
