摘要
在莫尔理论中如何引进中间主应力σ２的影响一直是长期困扰力学界的一个问题，由此产生了在σ－τ平面上难以界定某些状态下应力圆的破损界线。以静水应力σｍ对结合力和滑移的影响的观点，将二参数的莫尔定理修正为三参数形式后，分析了它在σ－τ平面上的应用，为引进中间主应力σ２的影响提出了新途径。
The influence of how to introduce intermediate stress σ2 in Mohr's theory has been the problem puzzling mechanics circle for a long time. Thus, It is of difficulty to define failure boundary of stress circle in some. It is suggested that in the light of the point of view of σm influence on binding force and sliding, Mohr's theory of two parameters be modified into of three parameters.The analysis on the application of this modification to σ-τ plane offers a new approach to introduce the intermediate stress σ2.
