Abstract
The Botlek railway tunnel is part of the cargo line “Betuweroute”. This line will run from the port of Rotterdam, The Netherlands, to Germany. The Botlek railway tunnel is a shield driven tunnel and consists of 2 tubes of 1800 m length. The tunnel was bored in typical Dutch soft soil. As part of the construction project, an extensive investigation of the dynamic response of the tunnel was carried out. The investigation is focussed on the dynamic effects from the source of the vibrations, the influence of a freight train on the tunnel to the propagation of the vibrations in the soil to the surface and piled foundations. For this research one tunnel ring is instrumented with accelerometers and strain gauges and different transducers have been installed in and on top of the soil and accelerometers have been placed in several foundation piles nearby the tunnel. Several aspects were in the experimental study investigated such as transfer function tunnelsoil and tunnel-foundation, ring-deformation, influence length of the tunnel, and induced stresses in the ground. Prior to the measurements several Finite Element Model calculations have been made to predict the vibrations in the tunnel and the transfer function tunnel-soil. The experimental results are then compared with the numerical modeling results. This paper presents some of the results of the experimental investigation and the comparison with the numerical results.

Dynamic Response of Bored Tunnel: Modelling and Testing

The Botlek railway tunnel is part of the cargo line “Betuweroute”. This line will run from the port of Rotterdam, The Netherlands, to Germany. The Botlek railway tunnel is a shield driven tunnel and consists of 2 tubes of 1800 m length. The tunnel was bored in typical Dutch soft soil. As part of the construction project, an extensive investigation of the dynamic response of the tunnel was carried out. The investigation is focussed on the dynamic effects from the source of the vibrations, the influence of a freight train on the tunnel to the propagation of the vibrations in the soil to the surface and piled foundations. For this research one tunnel ring is instrumented with accelerometers and strain gauges and different transducers have been installed in and on top of the soil and accelerometers have been placed in several foundation piles nearby the tunnel. Several aspects were in the experimental study investigated such as transfer function tunnelsoil and tunnel-foundation, ring-deformation, influence length of the tunnel, and induced stresses in the ground. Prior to the measurements several Finite Element Model calculations have been made to predict the vibrations in the tunnel and the transfer function tunnel-soil. The experimental results are then compared with the numerical modeling results.
