摘　　要：本文建立了平面比尺50、垂直比尺35的严家港泵闸工程闸下淤积物理模型,采用2014年7月实测水文资料开展了模型验证,同时对2009年3月至2014年5月的地形冲淤变化进行了验证。通过动床物理模型对拟建的严家港水闸导堤工程平面布置方案进行了试验研究。试验研究表明,闸下开挖引河后,在不建导堤情况下引河的月淤积量为1132 m^3,月淤积厚度为52cm;闸下引河两侧建100m导堤方案与无导堤方案相比引河淤积量减少近一半。因此,引河两侧建导堤非常必要,且多个方案比较导堤长度100m方案较优。The physical model,whose horizontal and vertical scales were 1：50 and 1：35 respectively,was setup to study on the silting downstream tidal barriers in Yanjiagang of Pudong District. The model was verified with field data observed on July in 2014 and then with siltation and erosionchange from March in 2009 to May in 2014 year. The general layout scheme of dikes engineering of Yanjiagang was investigated by this physical model. The study result showed that the monthly siltation amount was 1132 m3 without the dike engineering after digging the irrigation channel, and monthly siltation thickness was 52 cm. The siltation amount after building dikes with length of 100 meters on both side of irrigation channel was nearly half of that without dikes. So, it is necessary to build dikes on both side of irrigation channel and the dikes with 100 meters is better than others.
