运用概率统计的方法得出中梁山、缙云山两隧道的结构及材料实态概率特性，用随机有限元的方法，以岩石力学模式及“荷载—结构”模式两种途径，按围岩类别求得结构的荷载效应，最后以结构可靠度理论为基础对两座隧道建成时的可靠度进行评定。
Probability and statistics method is used to get the real probability of structure and material properties of two tunnels in Zhongliang Mountain and Jinyun Mountain. By means of stochastic finite element method, rock mechanics mode and load-structure mode, The load effect of the structure, and finally the reliability of the two tunnels is evaluated based on the structural reliability theory.
