摘　　要：城市地铁车站建设中经常会遇到富水地层或岩溶地区,其地下水极其丰富;随着地铁车站基坑开挖卸荷,作用于承压水上部的地层厚度逐渐减小,易造成车站基坑施工底部发生突涌灾害。为此,依托某地铁车站基坑工程突涌灾害,通过分析突涌水量变化过程,提出有效地突涌水治理措施,为类似工程建设提供重要的参考。in the construction of urban subway station,the water rich strata or karst areas are often encountered,and the groundwater is extremely rich.With the excavation and unloading of subway station foundation pit,the thickness of strata acting on the upper part of confined water gradually decreases,which is easy to cause the sudden gushing disaster at the bottom of station foundation pit construction.Therefore,based on a subway station foundation pit project gushing disaster,through the analysis of the change process of water gushing,put forward effective water gushing treatment measures,provide important reference for similar engineering construction.
