摘要
根据有限元正交设计算法，结合实例计算了房柱法采场顶板的可靠度和安全系数，其结果可为采场结构参数的选取及顶板可靠性评价提供依据。
Based on the orthogonal design algorithm of finite element and the practical example,the reliable level and safe coefficient for stope roof in room and pillar method are calculated,its result provided a foundations for selection of stope structrue parameters and evalution of stope roof reliability.
