OVERCOMING ABNORMAL EARTH PRESSURE IN KUBIKI TUNNEL

During the construction of the Kubiki Railway Tunnel in Japan, strong swelling earth pressure was encountered in a silt rock zone and the 230 M long heading was ruptured. It was decided to use the "short bench" method of excavation to reduce the time during which the section was unsupported by the concrete lining. Tunnel lining methods are briefly discussed. /TRRL/
