Protection Measures and Study on the Effect of Tunnel Boring Adjacent to Bridge Pile Foundation

Abstract

Abstract: This paper presents a case study is of Zhengzhou No.3 Metro Line Tunnel Boring adjacent to the pile foundation of a highspeed railway bridge. The Fast Lagrange finite difference code was adopted to calculate the impact of tunnel boring on the pile foundation. The results suggest that: the construction will induce additional vertical deformation and horizontal bending moment. This impact can be mitigated by the construction of isolation piles.

Key words: Zhengzhou Metro, Shielded Tunneling, Bridge Pile Foundation, Numerical Simulation, Isolation Piles
