一、刚性试验机在岩石力学研究中的意义最近十多年来,岩石力学有了巨大的进展.当前,由于工程实践的需要,人们对有关岩石破坏的力学特性的研究内容,已不只是限于强度及破坏前的变形特性,而已把范围扩展到破坏后的阶段,即对应力应变一一的全过程的力学性态进行研究. 人们对岩石破坏后的力学性态感兴趣,原因大致如次: First, the significance of rigid testing machine in the study of rock mechanics In the recent more than ten years, rock mechanics has made great progress. At present, due to the needs of engineering practice, people are not limited to research on the mechanical properties of rock failure. Intensity and deformation characteristics before failure, but has extended the scope to the stage after the destruction, that is, the mechanical properties of the whole process of stress-strain one by one. People are interested in the mechanical properties of rock after the destruction, the reasons are roughly like :
