一、序言自从1911年卡门〔1〕做了第一个岩石三轴试验之后,国外很多学者相继进行这方面的工作.特别是近廿年来,随着核爆和地震等方面研究的发展,随着超高压容器和密封技术的发展,促使岩石三轴试验研究有大的发展.美国的G riggs〔2〕、Handin〔3〕和日本的Mogi〔4〕等人在这方面作了大量工作.目前,美国已采用刚性试验机和伺服控制系统〔5〕,从而达到岩石三轴试验自动化. I. INTRODUCTION Since Carmen 〔1〕 did the first rock triaxial test in 1911, many foreign scholars have carried out this work in succession. Especially in recent years, with the development of nuclear explosion and earthquake research, The development of ultra-high pressure vessels and sealing technology has led to great progress in the triaxial test of rock. The American Griggs [2], Handin [3] and Japanese Mogi [4] have done a lot of work in this area. At present, the United States has adopted rigid testing machines and servo control systems [5] to achieve automation of rock triaxial tests.
