扰动段长江堤防防渗处置效果分析

Analysis on anti-seepage disposal effect of Yangtze River Dike in disturbed section

随着长江经济带不断建设发展,临江城市拥江发展,过江隧道不断增多,必将对长江堤防造成扰动,甚至可能出现险情。本文选取南京树人学校段江堤消险工程,分析出险原因,选定双排高喷桩垂直防渗墙及充填灌浆方案,通过工程质量检测、堤防渗流监测分析得出消险防渗措施实施效果良好,可供类似工程参考。

Cities near the river are developed based on the river with the continuous construction and development of the Yangtze River Economic Belt.The tunnels across the river are increased continuously,thereby causing disturbance to the Yangtze River Dike certainly.Dangerous situation may even appear.The river dike risk elimination project in the section of Nanjing Shuren School is selected to analyze the cause of the risk in the paper.The vertical impermeable wall and filling grouting schemes of double-row high-jet piles are selected.It is concluded that the risk elimination and seepage prevention measures are effective through the quality inspection of the project and the seepage monitoring of the dike,which can be used as a reference for similar projects.
