Abstract (en)
[origin: EP0515912A2] A tunnel-structure for travelling of high-speed trains is claimed wherein propagation of pressure disturbances generated by the train can be suppressed and especially emergence of acoustic shock waves can be avoided. This structure consists of the main tunnel for the trains and of many cavities arranged in the outside of the tunnel and in array axially with each cavity connected to the tunnel through a connecting passage(s).
