摘要
本文在目前已发表的岩石三轴应力应变试验资料的基础上,根据应变软化特点,提出了以塑性体积应变量表达的岩石稳定性判定准则。应用结果表明,该准则可以有效地反映岩石在不同软化状态下的稳定程度,从而可为工程决策提供更多的定量化信息。
Based on some available information about strain-softening behaviour of rocks, a stability criterion has been put forward. An example of its application shows that it can give an evaluation on the level of stability of rock in strain softening state.
