本文从加载系统的刚度大于岩石破坏过程变形刚度的绝时值时,就可以获得岩石应力一应变全图这一原理出发,论证了长江—500型三轴压力机能满足中硬岩石刚度要求,获得了大理岩、石灰岩的应力—应变全图。作者从能量分配的观点,认为岩石在破坏前后是一个能量储存与释放的全过程。岩石应力—应变全图说明:岩石破坏过程中,如果在某点能够控制变形的继续发展,则岩石可以再度处于稳定状态。
Based on the principle that the stiffness of the loading system is greater than the absolute value of the deformation stiffness of the rock failure process, the principle of a stress-strain map of the rock can be obtained. It is demonstrated that the Yangtze River-500 triaxial press can meet the requirements of medium- The marble, limestone stress - strain the whole map. From the viewpoint of energy distribution, the author thinks that rock is a whole process of energy storage and release before and after destruction. Rock Stress - Strain Figure shows: Rock failure process, if at some point to be able to control the continued development of deformation, the rock can be again in a stable state.
