摘　　要：在分析地下洞室围岩与支护结构不确定性基础上，作者提出应对支护结构进行概率极限状态优化设计，并应用改进的蒙特卡洛方法，导出了围岩稳定、喷锚支护以及二次混凝土衬砌的可靠性计算方法，该方法在微机上得以实现，可为围岩稳定评价，支护设计与校核提供理论依据和计算手段。On the basis of analysis for the indefiniteness of the Surroullding rock of atunnel opening and its composite lining support, the author puts forward a probabilisticlimit state optimum design of support for surrounding rock of tunnel. By using the improved Montecarlo's simulation method, the writer derives a reliability calculatingmethod for evaluating the stability of surrounding rock, the safety of shotcrete and rock-bolting support and its second coxcrete lining system. The calculating methods can beused in the design and check of support on personal computer.
