Estimating Remaining life of Underground Tunnel Concrete lining by Convergence Measurements

摘要

The authors propose a procedure for estimating stresses,load bearing capacity and remaining life of lining in long-term operated underground tunnels using the analytical calculations based on solving the plane elastic problem on slress-strain state of a non-circular variable-thickness ring restraining a hole in a linearly deformed medium,and by the in situ measurement data.
