一、问题的提出在实验室内,利用刚性加压设备对于岩石标本进行压缩试验,可以得到岩石标本的全变形曲线.该全变形曲线反映出岩石很多重要的力学属性,诸如压密过程、比例极限、应变强化、强度值、应变软化等等.这些力学属性无论是对于分析岩体的破坏机制,还是评价岩体的稳定性问题都是必需的第一手贫料.但实际上,直接用这些资料进行分析计算确不多.在目前的关于岩石一类介质的分析计算中,大体上可分二类:一是根据剪切实验给出的C、φ
First, the problem proposed in the laboratory, the use of rigid compression equipment for rock specimens compression test, you can get the full deformation curve of rock specimens. The full deformation curve reflects many important rock mechanical properties, such as compaction process, proportion Limits, strain hardening, strength values, strain softening, etc. These mechanical properties are necessary first-hand lean materials for the analysis of rock failure mechanisms, or for the evaluation of stability problems of rock masses. However, in practice, they are used directly. The analysis and calculation of these data are not much. In the current analysis and calculation of a rock medium, it can be roughly divided into two categories: First, according to the shear experiment C, φ
