| 摘 要： | 采用蒙特卡洛法对矿柱的可靠度进行了分析计算。根据莫尔强度理论建立了矿柱在多向应力状态下的极限状态方程，据矿和实测结果，采用柯尔莫柯洛夫法拟合检验了矿柱应力的变量分布类型和参数估计。

| Abstract: | This paper analyses the reliability of pillar by Monte Carlo method,establishes the limit state equation of pillar in the three dimension stress states and gives the distribution functions of stress of pillar by Kolmogorov goodness-of-fit test according to the data of measured stress of pillar.The distribution functions of stress in pillar are normal distribution N(,2).The result of calculation shows that the reliability index of stability of pillar is 2.472.77. |
