摘要
渗流引发坑内土体渗透破坏是引起基坑工程事故的一个重要因素。文中针对基坑工程渗流问题的特殊性,结合工程实例,从勘察阶段与施工阶段两方面阐述了基坑工程防渗帷幕的重大作用,指出了防渗帷幕施工质量控制的重要意义。
Seepage induced soil infiltration damage in the pit is an important factor causing accidents in foundation pit engineering.In response to the particularity of seepage problems in foundation pit engineering,combined with engineering examples,this article elaborates on the signif-icant role of anti-seepage curtains in foundation pit engineering from two aspects:survey stage and construction stage,and points out the im-portant significance of quality control in anti-seepage curtain construction.
