摘　　要：在对芜申运河三里埂汇流段的水文资料测量和收集的基础上,找出对于三里埂航道不利的水文条件,利用Mike21水动力模块建立水动力模型,对三里埂汇流段二维流场进行计算。计算结果表明:在设计航道地形条件下,高水位大流量时,设计航道内存在较大的横向流速,深坑处的流速和弯道环流仍然很大,将继续促进深坑的发展。模型通过对各种方案的比选和优化,提出了优化方案。Based on the hydrological data measurement and collection in Sanligeng confluence segment of Wuhu-Shanghai canal, the adverse hydrological condition in Sanligeng waterway was found out in this paper, and the hydrodynamic model was established by using the Mike 21 flow model to calculate two-dimensional flow field of Sanligeng confluence segment. Calculation results show that on the designed channel topography and high water mass flow condition, transverse flow velocity in designed channel is high. The circulating flow in bend near the pit is still strong, and it continues to promote the development of the deep pit. According to the comparison and optimization of all kinds of schemes, the optimized scheme was proposed.
