摘　　要：采用贴体正交坐标系下的平面二维水流数学模型,分析了重钢矿物码头工程的通航水流条件。经花朝门和汤家沱河段的实测水面线、水流流速分布验证,该模型可以较好地模拟复杂的河道边界条件下的水流情况,从而可预测河道的水流流场。计算结果与实测资料吻合较好,能满足工程通航需要。This paper analyzed the waterflow condition on navigation of Chongqing Mineral Terminal Project by using orthog- onal body-fitted coordinate and two-dimension shallow water mathematical model. Verification calculations were performed about the observed surface-line and velocity distributes of the river reaches of Huachaomen and Tangjiatuo. The result shows that it can accurately simulate the complicated boundary waterflow condition to predict the velocity field of project reaches. Therefore,the result corresponds with the practical measures and is reliable to meet the navigable demands of pro- ject.
