摘　　要：从2015—2019年世业洲左汊进口段的平面和断面的冲淤变化等方面,分析了镇扬三期部分工程和深水航道工程世业洲头部潜堤工程实施前后世业洲左汊进口段的地形变化。结果表明,工程的实施虽使世业洲汊道左兴右衰的状态得以改善,但世业洲左汊口门部位的河床发生较大的冲淤调整,其中原洲头左缘的2个贴岸深槽大幅淤积,而左汊口门中部及左侧河床出现了大幅冲刷,从而出现崩岸现象,最后针对因工程影响造成崩岸的现象提出建议。From the aspects of the erosion and deposition changes of the plane and section of left branch inlet section of Shiye Chau from 2015 to 2019,the topographic changes of the left branch inlet section of Shiye Chau before and after the implementation of the third phase of Zhenyang project and the deep water channel project of Shiye Chau head submerged breakwater project were analyzed.The results showed that although the implementation of the project had improved the status of the left rise and right decline of the Shiye Chau branch,the riverbed at the left branch entrance had undergone great scouring and silting adjustment.Among them,two deep grooves near the bank on the left edge of the original top Chau had been greatly silted up,while the middle part of the left branch entrance and the left riverbed had been greatly scoured,resulting in bank collapse phenomena.Finally,some suggestions were put forward for the bank collapse caused by the influence of the project.
