摘　　要：京杭运河韩庄一线、复线船闸共用引航道,船闸灌、泄水过程中形成非恒定流,水流十分复杂。为确保引航道内船舶航行和停泊安全,采用MIKE21水动力模型对船闸上下游不同水位组合情况下引航道复杂非恒定流进行深入研究,模拟计算引航道、靠船墩、口门区纵向流速、横向流速及环流分布情况。研究表明:泄洪条件下韩庄一线、复线船闸不满足通航要求;针对泄洪期存在的水力学问题,提出了有效工程措施——格栅及局部疏浚。The Hanzhuang line and twin-lane locks use the same lower approach channel and produce complex unsteady flow in filling and draining water. To ensure that the ships＇ safe sailing and berthing, we probe into the complex unsteady flow of lower approach channel in different upstream and downstream level combinations by MIKE21 hydrodynamic model, simulating the distribution of the longitudinal velocity, the lateral velocity and the circulation flow. The result shows that Hanzhuang line and the twin-lane locks don＇t meet the navigation requirements during the flood period. In view of the hydraulics problems of flood period, we put forward the effective engineering measures using grille and local dredging.
