Abstract: In the soft soil,the tunnel excavating often induce the deformation of the ground. Because the city tunnel constructs in the area where lots of buildings have been built crowdedly, the damage of the soil deformation around structure will be noticeable. At the same time, the structure which constructs in the vicinity of the tunnel will be able to cause deformation of the tunnel inevitably. This article mainly elaborated the influencing research results which include that the present tunnel construction cause the deformation to the building,the underground utilities,the pile foundation,the tunnel,the foundation pit and also the adjacent structure construction to the tunnel,proposing the topic and method which need further to study.
