以长沙某下临地铁的深基坑支护工程项目为依托,运用四排桩支护结构进行支护设计,解决了悬臂式支挡结构在嵌固深度受限时造成抗滑和抗倾覆力不足的相关问题,并通过理论分析和数值模拟论证了这种多排桩支护体系的安全性、可行性、经济性,以期为相关工程提供参考.
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.
