在三轴压缩条件下，得到了由多直径颗粒体材料构成的岩样的差应力-应变曲线的峰后斜率的表达式。
In triaxial compression, an expression for the post-peak slope of differential stress-strain curve of rock specimen that is composed of the material with different grain diameters is proposed.
这些力合成一个三轴不等的应力状态，相当一个以最短轴为半径的球状应力迭加一个差应力。
The stress state can be described by a sphere stress having the radius of the minimum axis with the superimposition of a differential stress between the maximum and the minimum axes.
