摘要/Abstract

摘要： 选取内摩擦角、黏聚力、泊松比、抗拉强度和弹性模量 5个因素，采用正交数值模拟试验方法，研究了围岩力学参数对巷道变形与破坏的影响。试验结果表明：对巷道表征变形量影响大小次序依次为黏聚力>抗拉强度>弹性模量>内摩擦角>泊松比；对围岩塑性区体积影响大小次序依次为黏聚力>内摩擦角>弹性模量>泊松比>抗拉强度。该试验结果较好地反映了理论分析结果，表明该方法不失为研究巷道变形与破坏的一种有效方法。

Abstract: This paper has presented a study on the effect of surrounding rock mechanical parameters on roadway deformation and failure with the method of orthogonal numerical simulation experiment. Re- searchers have selected 5 factors including internal friction angle, cohesion, Poisson’s ratio, tensile strength and Young’s modulus. The experiment results have shown that, according to the effect on roadway deformation, the sequence of these 5 factors is cohesion>tensile strength>Young’s modulus> internal friction angle>Poisson’s ratio; In terms of the importance to roadway failure, the order is cohe- sion>internal friction angle>Young’s modulus>Poisson’s ratio>tensile strength. This experiment results have well reflected the consequences of theoretical analysis, which has indicated that this method is highly effective for the study on the deformation and failure of roadways.
