摘　　要：为了预防长江堤防护岸工程受损或者大面积崩岸的发生,应定期对护岸工程进行监测和稳定性分析,必要时采取工程措施消除安全隐患。根据水下多波束测深技术全覆盖、高精度、高效率等特点,探讨了水下多波束测深系统的平面位置和水深测量精度,论述了基于水下多波束的护岸工程监测技术方法。并以湖北省监利县铺子湾护岸工程为例,采用水下多波束测深技术,连续2 a同一时段进行全覆盖扫测,根据2次扫测结果,采用3种不同的分析方法对堤防护岸工程地形变化进行分析。结果表明:护岸工程实施后深槽向右岸偏移,岸坡冲淤平衡,护岸工程稳定。The Yangtze River embankment should be regularly monitored and evaluated to prevent revetment works from damaging or bank collapsing.The authors discuss the accuracy of plane position and measurement depth of the underwater multi-beam sonar system according to its features such as full coverage,high precision and high efficiency.We also discuss the technique of monitoring revetment works by using underwater multi-beam technology taking Puziwan revetment project in Jianli county of Hubei province as an example.Full coverage sweeping survey was carried out for the embankment in the same period for two consecutive years.Having analyzed the topographic change of the embankment revetment by three different methods,we found that after the implementation of the revetment works,the deep groove moved towards the right bank,the bank slope erosion and deposition were in balance,and the revetment work was stable.
