Abstract

Reliability analysis of bolt-shotcrete support system is essential for the stability control of the underground tunnels. This paper presented a new analytical method for the reliability analysis of bolt-shotcrete support system. Considering the difference of the stiffness of each support unit, the bolt-shotcrete support structure was divided into two composite structures, and the structural performance function was developed based on the deformation coordination and stress condition of the two composite structures. Due to the nonlinear implicit characteristics of the structural performance function, Rosenblueth method was adopted to solve the function and estimate the failure probability of bolt-shotcrete system.
