| 摘 要： | 从随机观点出发，详细地分析了穿过含有软弱夹层岩体的巷道系统可靠性。巷道系统的破坏概率受巷道断面破坏概率、巷道长度、破坏区长度、弱层发生率、弱层长度的分布函数等多因素影响，不能简单地用巷道断面破坏概率反映整个巷道系统的质量状态。

| Abstract: | The paper from stochastic viewpoint evaluates the reliability of roadway system with certain length through one type of rock and the main rock including weak intercalation. The failure probability of roadway system is effected by varied factors such as the failure probability at a cross section of roadway, the given roadway lenth, the failure zone length,the occurrence rate of weak intercalation,the distribution function of weak intercalation length etc. The failure probabiltity of roadway can not simply indicate the quality state of roadway system. |
