引言 传统岩石力学实验系指在外加载荷条件下对岩石样品的强度、变形等物理力学特性的实验研究。仅借助于压机这一外加载荷对岩样的作用,去模拟研究地震过程及震兆变化,实验表明与天然地震前后的各种观测结果并非一致,故而,人们开始对膨胀力源作用下的岩石破裂力学过程研究发生了兴趣。例如,茂木清夫曾用电热丝外裹松香,研究热膨 Introduction The traditional rock mechanics experiment refers to the experimental study of the physical and mechanical properties of rock samples under the applied load. Only by means of the applied load of the press on the rock samples to simulate the seismic process and earthquake mechansim changes, experiments show that with the natural earthquake before and after the various observations are not consistent, therefore, people began to expand the source of force Interest in the study of rock fracture mechanics took place. For example, Mau Mau Cheong Fu has used electric wire wrapped around rosin, thermal expansion
