Recent laboratory studies of the flow and fracture of rocks under general triaxial compression are reviewed .New Developments in laboratory techniques have made it possible to measure three principal stresses and strains under general triaxial stress states ,in which all three principal stresses are different . Strength and ductility of isotropic rocks are markedly affected not only by the least compression σ3 ,although these two effects are rather additional in strength ,but opposite in ductility .The experimental results show that dilatancy is highly anisotropic rocks have been also measured under the general triaxial compression .In this case ,the effect of the intermediate compression markedly depends on the orientations of the weak planes. 相似文献

一般三轴压缩下岩石的流动和破坏 总被引:3,自引:0,他引:3
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。 相似文献
