Study of Influence of Subway Station Excavation on Existing Metro Deformation
Based on the excavation engineering of the subway station across the existing metro tunnel and in situ monitoring displacements, the comprehensive mechanical parameters were obtained by the back analysis. According to the geological engineering conditions and the construction scheme, the numerical model of excavating subway station was established. The structural deformation, settlement and railway incline law of the existing metro caused by new subway station construction were given. The relation of the pipe tent supporting effectiveness to settlement was obtained, and the key excavation step of producing the maximum settlements was given. The evaluation and the prediction of the safety construction and the safety operation on existing subway track were made. The research results had been applied to the subway station across the existing metro tunnel. The obtained results may be referenced in the design and the construction of similar engineering.
