莫尔-库伦理论的修正及应用

The Modification and Application of Mohr-Coulomb's Theory

针对莫尔 -库伦理论不考虑中间主应力对材料破坏影响的缺陷 ,提出了引进中间静水应力对抗剪强度和屈服面上摩阻力的双重作用 ,从物理意义上引进了中间主应力对剪切滑移的影响 ,把原来二参数的莫尔理论发展为三参数形式 ,弥补了莫尔 -库伦理论不足之处 .

The Mohr Coulomb's theory was modified by introducing static hydraulic stress, which has dual influences on yield face and shear strength. This two parameter theory was revised into a theory of three parameters. Finally, some examples were given.
