| Description | This paper presents results of an investigation which was carried out in order to analyze the stability of two tunnels. The tunnels were excavated in jointed rock masses of Jahrom formation. Due to structural feature and geology of the area the distinct element method was used to analyze the stability of tunnels. The code utilized according to this method was UDEC. The results gained from the numerical analysis show that the tunnel with smaller span, no major block fall occurs and hence a thin layer of shotcrete stabilizes the tunnel. However block falls and larger displacements were evident in the tunnel with larger span. The stability of the latter tunnel is achieved by using rock bolts in the sidewalls and a thin layer of shotcrete in the roof and sidewalls.
