| Abstract: | Shallow excavation technique has been widely applied in constructing urban subway in China. However, improper application of the technique may induce the upper layer being unstable or excessive deformation. Furthermore, it will hurt the safety of buildings and pipelines around the tunnel. Based on the safety analysis of urban subway tunnel by shallow excavation, the causation of hurting the safety is discussed. A set of indexes for safety valuation is presented. The paper also suggests countermeasures and methods for preventing disasters when designing, constructing and monitoring. |
