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。 Considering the various mechanical parameters, geometrical dimensions and the randomness and variability of the external load, this paper applies the structural reliability theory to the reliability design of the pillar structure. Considering not only the mean value of pillar strength and mine technical stress, but also taking into account their degree of dispersion and overcoming the shortcomings of the traditional single safety factor. With the reliability of pillar structure to evaluate the stability of pillar structure, the concept is more clear and reasonable.
