Abstract: 

Elasto-viscoplastic model is described first, and differential equation of visco-plastic strains is introduced with respect to time to use the model for the analysis of underground spaces include three linear and non-linear yield criteria: which is linear Mohr-Colomb, non-linear Hoek-Brown, and no-tension criteria. The corresponding relationships were derived for using in the computer program. The no-tension criterion is used for determination of the probable tension zones around the tunnel before Easto plastic analysis. A computer program was prepared in quick basic language capable of analyzing the ground around tunnels and underground spaces for linear and non-linear cases, and also to determine the stresses and strains in the tunnel surface in two-dimensional case. A horse-sheo shape tunnel was selected for analysis. One and two stage excavations, ground characteristics curve, pressure due to support system and the tension zones around the tunnel were analyzed and determined
