洪湖长江干堤虾子沟崩岸整治及水下监测分析

Bank collapse control and underwater monitoring analysis of the Xiazigou of Honghu in the Yangtze River Main Embankment

2017年汛前巡查中发现,洪湖燕窝镇虾子沟突发崩岸险情,该河段堤外无滩,河床冲深明显,崩窝有发展趋势,直接威胁长江干堤安全。崩岸发生后,专业测量队伍实施水下地形动态监测,用于调整抛投方案。本文对洪湖崩岸的发生、发展、治理及监测进行总结,为今后护岸工程实施提供借鉴。

During the pre-flood inspection in 2017,it was found that the bank collapse occurred in Xiazigou,Yanwo Town,Honghu Lake.There was no beach outside the embankment of this river section,the depth of the riverbed is obvious,and the collapse has a development trend,which directly threatens the safety of the Yangtze River main embankment.After the bank collapse occurred,the professional survey team implemented dynamic monitoring of underwater terrain to adjust the throwing plan.This article summarizes the occurrence,development,treatment and monitoring of the bank collapse of Honghu Lake,and provides a reference for the implementation of the bank protection project in the future.
