摘要
采用数值试验方法,研究了体积应力以及孔隙压与等效孔隙压系数的关系规律。结果表明:等效孔隙压系数与体积应力以及孔隙压呈双线性关系,等效孔隙压系数随体积应力的增大而减小,随孔隙压增大而增大。此结论与物理试验的结论相一致。
By numerical experiment measure, the relation of volume stress and hole press- coefficient of equivalent hole press is studied. It is found that relation of coefficient of equivalent hole press and volume stress, hole press is binary linear relation. Coefficient of equivalent hole press diminishes whenvolume stress enlarges and enlarges with hole press enlarges. The conclusion of numerical experiment and physics experiment is the same.
