0引言“土的剪切空间滑动面分析及各向异性强度准则研究[1]”(以下称之为“原文”)在分析土的多种强度准则基础上,指出Mohr-Coulomb、Drucker-Prager、Matsouka-Nakai强度准则实际上是通过土破坏时一个空间特征面上剪应力和正应力服从的条件而建立的,该空间特征面统称为剪切空间滑动面。其中,Mohr-Coulomb准则的空间滑动面与中主应力轴平行,其法向与大、小主应力方向夹角的方向余弦分别为
0 INTRODUCTION Based on the analysis of various soil strength criteria, it is pointed out that the Mohr-Coulomb (1) The Drucker-Prager and Matsouka-Nakai strength criteria are actually established by the conditions of shear stress and normal stress on a spatially characteristic surface under soil failure, which are collectively referred to as shear-space sliding surfaces. Among them, the space sliding surface of Mohr-Coulomb criterion is parallel to the middle principal stress axis, and the direction cosine of the angle between the normal direction and the direction of major and minor principal stress is
