【摘要】 对已完成的室内单轴岩石抗压试验结果进行了初步的研究，在采用随机－模糊统计的方法确定岩石单轴抗压强度时发现，随机－模糊统计比通常的随机统计方法得出的数字特征指标的变异性要小。以实际出现的事件可能性最大原则为出发点，克服了传统的随机统计仅仅单独地顾及了试样的随机性而没有顾及试样的模糊性，为工程实践中岩石抗压强度的指标提供了更为实用的分析方法。更多还原

【Abstract】 The experimental results of rock compression strength are primarily studied. The uni-axial compression strengths of rock are established by the random-fuzzy method. It is exposed that the variation of statistic parameters obtained by the random-fuzzy statistic method is smaller than that by the random statistic method. The random-fuzzy statistic method overcomes the shortcoming of traditional random statistics method, which can only consider the random property of the sample but not the fuzzy property of the sample. The random-fuzzy statistics method is useful analysis method to determine the rock compression strength in practical engineering.更多还原
