摘　　要：选取长江口航道整治建筑物近年来典型损坏修复工程实例,介绍长江口航道易冲刷河段整治建筑物修复设计及工程质量控制措施。针对航道整治建筑物堤身塌陷、护底冲刷、灯桩基础倾斜等代表性损坏,查明原因,研究确定修复措施,提出施工质量控制要点。修复工程实施后,整治建筑物监测分析表明,损坏部位得到有效修复,周边地形河势稳定,实现了预期修复目标。Through the examples of the typical repairing projects of regulation structures in the Yangtze River estuary waterway in recent years,the remediation measures and the quality control standards of the regulation structures of the Yangtze estuary deepwater channel were introduced in this paper.In view of the representative damages such as embankment collapse,bottom scouring and collapse of the dikes or light beacons,the reasons were analyzed.The repair measures were studied and determined,and the key points of construction quality control were put forward.After the implementation of the repairing project,the monitoring analysis shows that the damaged parts have been effectively repaired,the surrounding terrain and river regime are stable,and the expected restoration goal has been achieved.
