摘要: 本文通过实验,研究了一种介于岩石与土之间的软岩——粉砂岩在不同应力状态和应力路径下的基本力学性质、时间效应和交叉效应,提出了一维率相关型本构方程、三维体积应变本构方程以及破裂准则。

Abstract: The fundamental mechanical properties, time and crisscross effects of a kind of siltstone under different stress states and along different stress paths are studied with laboratory testing. A failure criterion, constitutive equations with one dimensional rate dependence and three dimensional volume deformation are proposed in this paper.
