摘要
考虑岩体的各种力学参数、几何尺寸以及外部荷载作用的随机性和变异性，本文应用结构可靠度理论对矿柱结构进行可靠性设计。不仅考虑了矿柱强度和矿技应力的均值大小，同时也考虑了它们的离散程度，克服了传统的单一安全系数的缺陷。用矿柱结构的可靠度来评价矿柱结构稳定性，概念上更明确，合理。
Based on the structural reliability theory,this paper gives the reliability design method for pillars. Because of the random parameters of rockmass mechanics,it is reasonable and clear using the reliability index to evaluate the stability of pillars. The result shows that the reliability index of the stability of pillars is 2. 29 to 2. 77.
