the underground tunnel excavation often induces ground deformation. Due to city underground excavation tunnel lies in area with dense and intensive buildings
the damage of the soil deformation to around structures is noticeable. On the other side
the construction of adjacent buildings will cause loading and deformation to the existing tunnel inevitably. This article mainly elaborate the research achievements about the influence of soil deformation caused by underground excavation on the buildings
the pile foundation
the underground utilities
the existing tunnel
the foundation pit
and the influence of the adjacent structure construction on the exiting tunnel. The future direction and method of this study are also proposed.
