一、引言在天然条件下,岩石的破坏和流动是在复杂的组合应力下产生的.应力状态的影响在岩石力学里是个基本课题之一.为了研究这一影响,在各种组合应力状态下,进行了许多岩石变形的室内实验。
I. INTRODUCTION Under natural conditions, rock failure and flow are generated under complex combined stress. The influence of stress state is one of the basic topics in rock mechanics. In order to study this influence, under various combined stress states Many indoor experiments of rock deformation were conducted.
