In recent years， the foundation pit engineering gradually presents the characteristics of "large ， deep ， tight and close". This puts forward new requirements and challenges to support and stop water in the process of deep foundation pit excavation. Effective curtain for cutting off drains is not only an important means to prevent groundwater infiltration ， but also relates to the quality and safety of foundation pit engineering. Water curtain leakage not only affects the construction progress of foundation pit， but also endangers the safety of surrounding buildings， pipelines and other municipal works ， and even causes the collapse of the whole foundation pit， thus causing serious safety accidents and property losses. Therefore ， this paper makes a comparative analysis of 1下载后可任意编辑different construction techniques ， applicable conditions and advantages and disadvantages of water-stop curtain， so as to provide references and suggestions for the selection of water-stop curtain techniques in th...
