摘要：With the development of metro, the construction of subway tunnel and station have to cross the crowded building group. For different crossing existing structures, such as undercrosing, uperossing and side-crossing engineering, the adjecent existing structures would be influenced unavoidably. It is important for adjecnt existing structure that the deformations and stabilities of them are controlled during the metro construction. So, according to one side-crossing engineering project, based on numerical simulation and model test method, the deformation of support structures of metro station are studied, and the impact of station side-crossing on adjecent existing undergroud structures are discussed in different construction methods. Through those researches, it can be founded that the deformation law and stability of support structures are revealled and the the main influencing factors are expounded. At the same time, the internal force characteristics of support structures and incline deformation law are argumented and the contributing factors are analysed for different construction method, such as open excavation construction and cover excavation reverse construction.
