Abstract：
Subway stations are usually shallowly-embedded structures, which are susceptible to variation of environmental condition. The effect of change of groundwater level and emergence of new building on the internal forces of a subway structure and its pile foundation was analyzed. The results show that the forces of the middle and base floors increase as the groundwater level rises and the forces at the pile heads vary from pushing forces to dragging forces. The effect of new building emerging on one side of the station is significant than that of new buildings emerging on both sides.
