Study on the supporting design of deep foundation pit with four-row piles structure next to subway tunnel downwards
Based on a deep foundation pit support project in Changsha,which is next to the subway downwards,the four-row pile support structure is used for support design,which solves the related problems of insufficient anti sliding and anti overturning forces caused by the cantilever support structure when the embedded depth is limited.Through theoretical analysis and numerical simulation,the safety,feasibility and economy of this multi-row pile support system are demonstrated,and the conclusions obtained are expected to provide reference for related projects.
