EFFECTS OF GROUND CREEP ON A LINING INSTALLED IN A CIRCULAR TUNNEL

The analysis of the interaction between a thin, circular, elastic tunnel lining and the surrounding visco-elastic ground has been studies. In strong ground, such as rock, it is usual for the lining to be installed after the tunnel has been excavated and if the rock subsequently creeps then loads will be induced in the lining. The magnitude of these loads will depend on the creep properties of the rock, the elastic properties of the lining, the time after excavation at which the lining is installed as well as upon the initial stress state of the ground. A parametric study has been carried out to investigate these effects.
