Abstract: For further study the mechanical properties of the axisymmetric roadway surrounding rock, Hoek-Brown criterion and non-associated flow rule are used as elasto-plastic analytical method of circular roadway by considering the effect of the rock dilatancy characteristics and elastic deformation in the plastic zone. Using the conditions that the stress is continuous at the elastic-plastic interface, a fully analytical solution for Hoek-Brown failure criterion is proposed for the displacement and radius of plastic zone. Illustrative examples are given to demonstrate the performance of the proposed solution and compare with the Mohr-Coulomb failure criterion. The results obtained by the proposed solution indicate that, the M-C and H-B criteria are in good agreement when the dilatancy characteristic is small. With the increase of dilatancy coefficient, the agreement of the M-C and H-B criteria is failing and the displacement of plastic zone increases with the increase of dilatancy coefficient. At the elastic-plastic interface, the displacement of the plastic zone is approximately equal based on H-B criterion with different dilatancy coefficients, while the M-C solution is not equal, which theoretically proves the accuracy of solution.
