Abstract

In this paper the pressure-wave generation and propagation in a rail tunnel and the influence of an extended tunnel portal on this phenomenon are discussed. A new test facility is introduced, which was built in 2010 and allows the investigation of the pressure waves due to train-tunnel entry. It is a moving-model rig, which enables to investigate a realistic tunnel passage of the train. The first measurements of the pressure waves generated by a high-speed train entering a tunnel, which were done with the new facility, and their results are presented here. Furthermore a hood acting as extension of the tunnel portal is studied.
