The Mohr-Coulomb criterion is used in this paper to describe the strength of rock mass in tunnel of civil engineering. The position of a stress point on this envelope is controlled by a non-associated flow rule for shear failure, and an associated rule for tension failure. Excavation of tunnel will lead to the redistribution of stress in rock mass, in order to compare the analytical and numerical solution of rock mass response to predict the safety degree of underground tunnel, to predict the safety degree of tunnel, some calculations are done by theoretical and numerical methods. The comparison results can give guidance for the real practice
