基坑开挖对临近地铁隧道影响分析及控制

Analysis and Control of the Impact of the Excavation of Foundation Pits on Adjacent Subway Tunnels

随着城市化进程的不断进行,地铁成为人们日常出行的工具,城市的不断建设发展,导致临近地铁的工程不断增加,新工程的建设必然会对既有地铁隧道产生影响。基坑工程作为新建工程的基础工程,会引发土层结构的变动,从而对既有地铁隧道结构产生一定的影响。因此,基坑开挖时应当充分考虑对地铁隧道产生的不利影响,积极探寻控制措施。

With the continuous progress of urbanization,the subway has become a tool for people's daily travel.The continuous construction and development of cities have led to an increasing number of projects near subways,and the construction of new projects will inevitably have an impact on existing subway tunnels.As the foundation engineering of new projects,foundation pit projects will cause the changes of the soil structure,and then have a certain impact on the structure of existing subway tunnels.Therefore,when excavating foundation pits,adverse effects on subway tunnels should be fully considered,and control measures should be actively explored.
