| 摘 要： | 通过建立一维非恒定水流泥沙数学模型，对规则断面引航道中的水流泥沙运动规律及淤积特性进行了数值模拟计算，并对影响感潮河段船闸下泥沙淤积的各种因素(如干支流水位差、开通闸水头差、主流潮差等)进行了深入分析和研究。研究结果可为有关工程设计及运行管理提供参考。

| Abstract: | Siltation is a common problem in approach channels of river branches in tidal areas, and it is very complex because of many influencing factors. A one-dimensional unsteady numerical model is developed to simulate the movement of flow and sediment in a regular approach channel and to analyze the influence of some factors on siltation. The results supply a scientific basis for the design and management of projects. |
