本文叙述了三轴试验中岩石的应力状态及破坏性质的改变,指出了中间主应力α_2对强度影响的区间性.文中论证了试验过程中保持应力状态类型参数a一致的必要性和重要性,并提供了利用两种砂岩进行探索性试验的结果.文中对作者所设计的330型岩石三轴试验机也作了简单的介绍.
This paper describes the change of stress state and failure property of rock in triaxial test, and points out the interval of the effect of the intermediate principal stress α_2 on strength. This article demonstrates the necessity and importance of maintaining the consistency of the stress state type parameter a during the test. The results of exploratory experiments using two kinds of sandstones are provided. The author also briefly introduces the model 330 rock triaxial tester designed by the author.
