摘要: 分析了现有关于2种类型的岩石应力-应变全过程曲线,在此基础上,根据大量基于MTS系统的室内岩石力学试验结果,运用能量准则分析了II型曲线的合理性,指出II型曲线由于采用了一种更为稳妥的控制方式,能够反映岩体破坏的真实情况,并可以为研究岩爆提供一个新的切入点。

关键词: 全过程曲线 , II型曲线, 能量准则

Abstract:  The existing discussion about the two types of the rock whole process stress  strain curve is analysed. According to a large number of test results based on the MTS trial system, the rationality of the class II curve is analysed using energy criteria. And owing to a more stable control method, the class II curve can reflect the real situation of rock mass destruction, and can provide a new starting point to study the rock burst.

Key words:  whole process curve , the class II curve , energy criterion
