【摘要】 作者在采场巷道围岩分类的地质力学分类基础上，考虑了岩体分类因素的不确定性，首次提出了分类的概率统计方法。本文提出了各类因素定量评分标准以及分类指标修正准则，研究了基于围岩分类指标确定岩体强度和变形参数的方法。小官庄铁矿西区中的应用表明，该方法具有一定的实用价值和应用前景。更多还原

【Abstract】 A probability analysis method is for the first time proposed by the authors,taking into consideration of the uncertainty of factors for classification of rock masses on the basis of geomechanical classification.The paper describes the standards for quantitative analysis of all the factors for classification,and criteria for modifying classification indices.A method for determining rock strength and deformation parameters is investigated based on rock masses classification indices.Its application in the western area of Xiaoguanzhuang iron mine shows that it can be applied in practice.更多还原
