摘要
对于采用锚喷支护结构的地下洞室,依据弹塑性小变形理论,提出了应对支护结构进行概率极限状态优化。应用改进的蒙特卡洛方法,建立了地下洞室围岩稳定、锚喷支护结构与混凝土衬砌的可靠性计算公式,从而为地下洞室围岩稳定性评价、以及支护结构设计提供了可靠的理论依据。
According to the elastoplastic small deformation theory,the probability limit state optimization which applies improved Monte-Carlo method to deal with underground caverns which have been support,the reliability calculation formula of underground caverns surrounding rock stabilization,shotcreting and anchoring structure with concrete lining,is established in order to provide credible theory of underground caverns surrounding rock stabilization evaluation and timbering structural design.
