Abstract

A discussion is presented of the numerical analysis, based on the finite element method, of the time dependent effects that develop when a tunnel is driven in a rock mass characterized by a viscous behaviour. First, the so called swelling and squeezing phenomena are described considering in particular rocks containing clay minerals. Subsequently the discussion is focused on the squeezing behaviour, i.e. on the time dependent increase of the shear deformation which develops with minor volume changes. Some simple linear and nonlinear constitutive laws are presented able to describe this phenomenon and their use in the solution of boundary value problems by means of the finite element method is discussed. Finally, the results of some numerical analyses are presented that illustrate the effects taking place around tunnels driven into squeezing rocks.
