摘要
Abstract
Taking a foundation pit adjacent to an interval tunnel as an example,by reasonably optimizing the foundation pit design scheme and strengthening the protection measures of the adjacent subway interval tunnel,it is found that the verti-cal displacement of the adjacent interval tunnel is obviously greater than the horizontal displacement during the construction of the retaining structure by using midas GTS NX three-dimensional finite element analysis software;during the excavation of foundation pit,the horizontal and vertical deformation of the adjacent tunnel is opposite to the deformation direction of the re-taining structure,and the vertical deformation of the tunnel changes from settlement to uplift,and the horizontal displace-ment is obviously greater than the vertical displacement during the excavation of foundation pit.The research results can pro-vide reference for similar engineering construction.关键词
