摘要

根据主应力可分解为静水应力和偏应力，以及它们在应力莫尔圆和变形方面的相关性，推导出修正的莫尔-库仑理论的数学表达式。从理论上解决了库仑理论和莫尔理论存在的许多缺陷，特别是中间主应力对材料抗剪强度的影响。它的四参数准则的计算结果与一些混凝土的试验数据相当吻合。

Abstract

According to the decomposition of principal stress into hydrostatic stress and deviatoric one as well as to the correlation between them in Mohr’s circles and deformations

the paper deduces the mathematical expression of modified Mohr-Coulomb’s theory. This expression solves many shortcomings of Coulomb’s theory and Mohr’s theory theoretically and particularly

it describes the influence of intermediate principal stress on shear strength. At the same time

a four-parametric criterion is established. The computing results using this four-parametric criterion are quite agreement with those obtained from tests on concrete specimens of different kinds.
