长江堤防防渗加固技术分析

堤防工程的防渗加固操作是长江流域防汛除险的一项关键性措施。参考醒目工程的实际案例,文章针对多头小直径的深层搅桩方案的防渗墙、临水坡区域实施铺设复合型土工膜、塑性类型的混凝土防渗墙施工等防渗方案实施深入地阐述和讲解,同时比较各类防渗解决方案的优势以及不足,指出各类方案的使用场合,为长江流域的堤防防渗加固模式的选取提供有效的参考和借鉴。

The anti-seepage and reinforcement operation of the dike project is a key measure for flood control and risk control in the Yangtze River Basin. With reference to the actual cases of eye-catching projects, this paper makes an in-depth exposition and explanation of the anti-seepage schemes such as the impervious wall of the deep mixing pile scheme with multi-head and small diameter, the composite geomembrane laid in the area near the water slope, and the construction of plastic concrete impervious wall. At the same time, the advantages and disadvantages of all kinds of anti-seepage solutions are compared, and the suitable application occasions of all kinds of schemes are pointed out. The purpose of this paper is to provide effective reference for the selection of anti-seepage and reinforcement mode of dikes in the Yangtze River basin.
