SaeidiA. ElyasiS. Maleki anal A. This study presents a closed form solution around underground openings based on the four rock failure criteria.

The results jepan sex hd the closed form solution are compared to the numerical method to establish the solution. The Tresca, Mohr-Coulomb, Underground and generalized Hoek-Brown failure criteria are used to determine stress distribution and plastic zone around the circular space.

The solutions are implemented in three dimensional distinct element code 3DEC and assessed numerically. Also, the parametric study using these criteria is presented.
