People Square Station of Shanghai Metro No.8 is a parallel transfer station

of which excavation is adjacent to People Square Station of Metro No.1. Monitoring data indicate that the constructed station inclines reversely during adjacent excavation. Through FDM numerical simulation

displacement transfer behavior of excavation is analyzed; and displacement transfer law of excavation adjacent large stiffness underground building

is analyzed. The results show that a large stiffness underground building makes a great difference of displacement that: (1) block effect

which results to minish the displacement of retaining structure; (2) cutting off the path of soil displacement transfer

which changes soil’s displacement and brings on building’s inclination reverse to pit.
