| Abstract: | This paper took the deep foundation pit of an adjacent subway structure as an example,using the method of equivalent stiffness,the fender pile was equivalent to the underground continuous wall to build the finite element model and three dimensional numerical analysis of groundwater seepage in foundation pit is carried out,analysis the impact of groundwater seepage pit on adjacent subway structure.The optimization and improvement measures are put forward to reduce the influence of groundwater seepage,which is of some significance in guiding engineering practice. |
