摘要
岩石试件在单轴匠缩条件下的应力-应变全过程曲线,在岩石力学研究与工程应用中有着重要意义。本文对“Ⅰ型”与“Ⅱ型”峰值后区曲线的形成条件进行了分析,并根据能量观点和最新的试验结果讨论了“Ⅱ型”曲线的不合理性,同时对峰值后区特性提出了新的见解。本文中的最新试验结果是在三位作者合作研制的自适应控制岩石力学试验机上作出的。
The complete stress-strain curve of rock specimens under uniaxial compression is of sigaificant importance in the geomechanical researchand engineering application. In this paper analysis is made on the conditions, under which the post-failure curves of type Ⅰ and type Ⅱ are formed, and from the viewpoint of energy, based on the newest experimental data, a discussion is conducted, which shows the irrationability of the curve of type Ⅱ. A new opinion on the post-failure behaviour is presented.The newest experimental results used here are obtained by means of the test machine of adaptive control for the purposes of rock mechanics, which is developed by the authors of paper.
