Abstract
In this study, the relationships between the displacement and stress of the tunnel using various analysis methods were compared with monitoring results carried out during construction and maintenance monitoring. The behavior of tunnel were measured in the subway tunnel passing comparative soft the weathering and analyzed both security and mechanical characteristics of the tunnel lining. With the results of simplified monitoring observed in top heading and bench excavation tunnel, it is confirmed that the crown settlement is larger than the surface settlement. it is interesting to note that the crown settlement and the crown shotcrete lining stress are widely used monitoring items for the back analysis. It is analyzed that the residual water pressure applied in the drainage type tunnel is reasonable.
