摘    要:本文从损伤力学的基本概念出发,应用Mohr-Coulomb破坏准则,得到了抗压强度与损伤因子的关系,同时用统计分析方法,建立了试件内部孔隙分布的一种基本模型,进一步推导出孔隙率对试件抗压强度影响的理论关系,该关系与试验结果颇为一致。

关 键 词:砂岩  孔隙率  强度  损伤力学

Abstract:From Viewpoint of damage mechanics,the relationship befween compressive strength and damage factor is obtained by appling Mohr-Coulomb damage creteria. Meanwhile,a basic model for pore distribution in sample is established by statistical analysis method. Theroy relationship of effect of porosity on sample strength is reported further. The relationship is consistent with test results.
Keywords:sandstone  porosity  strength  damage
