Adjacent Shallow-Buried and Mined Tunnel Building Safety Assessment in Complex Surroundings

摘要：

Urban Tunnel Excavation on the impact of the urban environment has attracted peoples attention. How to reduce the tunnel construction to effect of the surrounding environment, especially, the impact of the existing structures has become a very important study topic. Compared with other common structures, buildings are more sensitive to external effect because of the particularity and complexity of structure, and have more complicated deformation mechanism, and the accident consequence are more serious correspondingly which may bring more serious accident consequence correspondingly. The paper described the construction method of calculating damages, and introduced the critical strain and deflection ratio and other parameters calculations, gave the building damage level and the relationship between the importance of building and the corresponding risk level. Through analyzing a project the paper calculated the risk level of the building by three-stage method, which have a clear guideline to the construction.
