Abstract

This paper deals with numerical modelling of rock failure around an under-
ground tunnel under remote seismic loading. A continuum based numerical model consisting of a viscodamage-viscoplastic material model for rock and a polygonal finite elements scheme to model the wave propagation in rock is presented. The numerical simulations of an underground opening under a compressive stress wave demonstrate that this approach, despite the limitations of the continuum approach in modelling rock fracture, predict many important features of the rockburst (ejection) into the tunnel in computation times fractional to those of the particle methods.
