Abstract:

In this study, we build the analytical models of reliability index on anchor-shotcret support structure of tunnel which is non-symmetrica. Considered functionís high non-linear, the reliability index computation is adopted by Monte-Carlo method. The calculation results show that reliability index decreases when variation coefficients of crustal stress, cohesive force, inner friction angle, thickness of shotcrete layer, concrete compression strength and extension strength of anchor-shotcret and anchoring force increased and reliability index increases when variation coefficients of tunnel radius and final origin angle of broken wedge increases. Variation coefficients of inner friction angle, tunnel radius and final origin angle of broken wedge has outstanding influence on reliability index and then thickness of shotcrete layer, concrete compression strength, cohesive force, crustal stress and anchoring force. Reliability index increases with lateral pressure factor increased. Reliability index rapid decreases with crustal stress increased.
