Abstract

The time-dependent behaviour of an elasto-visco-elastic medium is investigated and examined further. Numerical analysis of an advancing tunnel is performed via isotropic axisymmetric finite difference modelling (FLAC by Itasca, 2011) to examine the interaction of tunnel advance and instantaneous closure, short to medium term primary creep and longterm secondary creep. In addition, a new approach to calculate LDPs is presented taking into account both the tunnel advance and the time-dependent rockmass behaviour.
