Model experiments on the influence of tunnel hood cross-sectional area on the reduction of the pressure gradient of the compression wavefront in high-speed railways

Micro-pressure wave emission from tunnel portals in high-speed railways causes environmental issues. Tunnel hoods installed in the tunnel portals reduce the micro-pressure wave emission by reducing the pressure gradient of the compression wavefront generated in the tunnels. This study investigated t...
