Numerical simulation of compression wave propagation in German slab-track tunnels

Last updated on 01 June 2016 3:44

A train entering a tunnel causes a micro-pressure wave (MPW) that radiates outward from the tunnel. The peak value of the MPW is approximately proportional to the maximum value of the pressure gradient of the compression wave in the tunnel. Prediction of the MPW requires evaluation of the steepening the...
