摘　　要：长江镇扬河段近百年来变化较为剧烈,近年来世业洲左汊分流比持续加大。本文在实测资料的基础上,通过河床演变分析和河床冲淤计算,对世业洲左汊进口段幸福河口崩岸的成因进行了分析。结果表明,崩岸是在地质条件、河势条件、12.5m深水航道工程鱼骨坝挑流共同作用下的结果,今后需加强该段的河道地形监测,预防新崩岸的发生。此研究对该河段今后的监测和治理具有一定的指导意义。Since Zhenyang reach of Yangtze River has changed relatively sharply over a hundred years,and the split ratio of Shiyezhou left branch has increased in recent years.The causes of the bank caving of Shiyezhou left branch inlet reach Xingfu estuary are analyzed based on the measured data in the paper through riverbed evolution analysis and riverbed scouring silting calculation.The results show that bank caving is the result of the common action of the geological conditions,and the river regime conditions and fish-bone type dividing dike deflecting flow of the 12.5m deep sea channel project.The river topography monitoring of the reach needs to be strengthened to prevent the occurrence of new caving in the future.The study has certain guiding significance for the future monitoring and management of the river section.
