GROUND SUBSIDENCE DUE TO EXCAVATION AND EARTH-PRESSURE BEHAVIOUR IN TUNNELS

During the excavation of a tunnel in the soft ground of thin earth covering, the subsidence of ground and strong earth-pressure on the tunnel often cause major difficulties. Now JNR has experienced and is experiencing construction of several tunnels with a thin earth covering which is expected to subside due to excavation. This report purports to describe the mode of subsidence of ground and earth-pressure, and some proposals of safeguard for such tunnelling.
