| Abstract: | In this paper,based on the stochastic block theory of the rigid body limit balance and the strength theory of ground stress and the second stress in surrounding rocks, limit state equation is established.Stability of non pressure tunnel surrounding rocks is analyzed by using reliability method.The result is feasible.Satisfying solution is obtained in stability of non pressure tunnel surrounding rocks during the establishing period and the repairing period. |
