Effect of Shield Tunneling on High-Speed Railway Bridges under the Influence of Train Operations

Abstract:

This paper is based on one project of Metro shield tunnel across a high-speed railway bridge. In the study the impact of train operations is taken into account, the finite-element method is adopted to analyze effect of shield tunneling. The conclusions indicate that according to the different tunnels and relative positions of pile, the excavation of the tunnels would have different effects on pile foundation. When the construction of shield across the bridge, the nature of the soil and will have an effect on deformation and stress of pile. Due to tunnel excavation of bridge internal force on bridge attached to the forces of good roles and bad role. Additional deformation of the beams and the additional forces are very small, so they will not affect the bridge work.
