摘　　要：无为大堤白玉池段位于位于长江黑沙洲河段,上自民主村,下至小圩拐,全长2.6 km。该堤段直接临江,滩地狭窄,江面宽阔,浪程远大,上段近岸河床岸坡冲刷,局部堤段黏土覆盖层薄,是无为大堤老历史险工之一。该段经逐年维修加固并相继实施了填塘固基、堤身加培、块石护坡、钻探灌浆、截渗槽、防汛公路等工程项目后,虽保证了工程安全度汛,但在汛期高水位时,堤脚附近仍然容易出现散浸渗水现象。主要对该段近年来实施的除险加固工程措施进行阐述,并对安全现状进行分析、提出建议。Baiyuchi section of Wuwei Embankment is located in the Heishazhou section of the Yangtze River,with a total length of 2.6km from Mingzhu Village in the upper part to Xiaoweiguai in the lower part.Baiyuchi section directly faces the river,with narrow shoals,wide river surfaces,and long wave paths.The upper section of the embankment is washed by the bank slope of the nearshore riverbed,and the clay cover layer of some sections is thin.It is one of the historical and dangerous works of Wuwei embankment.This section has been repaired and reinforced year by year,and has successively implemented engineering projects such as pond filling and foundation stabilization,embankment reinforcement,block stone slope protection,drilling and grouting,antiseepage ditch,flood control road,etc.Although ensuring the safety of the project during the flood season,it is still easy to experience scattered seepage near the embankment foot during high water levels during the flood season.This paper mainly elaborates on the risk elimination and reinforcement engineering measures implemented in this section in recent years,analyzes the current safety situation,and puts forward suggestions.
