ICE LAYERS IN TUNNELS

Abstract

Since the formation of ice layers in tunnels is due to a combination of subterranean water and cold temperature, the methods of draining such tunnels should be designed to prevent the seepage of water through the tunnel lining and to maintain an above-freezing temperature. It is therefore recommended that icing on railroad tracks in tunnels be prevented by ground fastening, the drilling of damming wells, the installation of derivation troughs as well as heating devices to maintain a warm temperature.
