止水帷幕深度对地下水渗流规律的影响分析

Analysis of influence of water-stop curtain depth on groundwater seepage law

近年来,海绵城市的建设越来越被人关注,而城市中高楼大厦的止水帷幕结构,会对深层地下水渗流产生一定的影响。以武汉某深基坑工程为研究背景,考虑地层实际分布情况,利用FLAC3D软件构建数值模型,研究有无止水帷幕,止水帷幕是否落底以及不同深度止水帷幕对地下水渗流变化规律的影响,为实际工程止水帷幕设计提供参考依据,为海绵城市建设提供新思路。

In recent years, more and more attention has been paid to the construction of sponge city, and the water-stop curtain structure of high-rise buildings in the city will have a certain impact on the seepage of deep groundwater. Taking a deep foundation pit project in Wuhan as the research background and considering the actual distribution of strata, this paper constructs a numerical model by FLAC3D software to study whether water-stop curtain exists, whether water-stop curtain falls down and the influence of water-stop curtain of different depths on the variation law of groundwater seepage, which provides a reference basis for the design of water-stop curtain in actual project and provides a new idea for sponge city construction.
