| 摘 要： | 本文基于内时理论的基本网络,利用四组内变量对软岩介质变形规律进行了分析与描述。从格朴斯(Gibb’s)自由能形式出发,把“塑性应力”的概念引入内时本构体系,获得一组新的内时本构方程。理论分析表明,该组本构方程能较方便地反映岩土介质广泛存在的不可逆非线性变形、剪胀(扩容)、交错效应等复杂的物理力学现象。理论计算和实验结果相吻合。

| Abstract: | Based on concept of endochronic theory and “plastic stress”, a new endochronic constitutive equation of soft rock is obtained by using the four groups of internal variables which represent different laws of displacement of soft rock. Compared with the experimental results the theoretical prediction is satisfactory. |
