摘要
在岩体工程中,岩石的力学特性对工程稳定性的影响较大,特别是岩石的时间效应和累积疲劳效应。为了避免岩石因蠕变和疲劳而引发灾害,学者们对岩石的蠕变及疲劳的机理和因此产生的物理力学性能的变化做了大量研究。通过总结岩石的蠕变和疲劳的性质、机理,从损伤的角度,着重对岩石蠕变和疲劳损伤的研究进展进行介绍。借鉴金属蠕变-疲劳交互作用研究的成果,对岩石蠕变-疲劳交互作用的性质、机理以及研究方法做了简单的探讨,为盐岩储气库的安全稳定研究提供参考。
Due to the complexity of underground environment,the safety and stability of rock engineering are strongly influenced by the mechanical properties of rock. In order to avoid the disaster resulted from the creep and fatigue effects of rock,a lot of researches have been done on the properties of creep and fatigue of rocks. Based on the previous research results,it was summarized the properties and mechanism of creep and fatigue of rock. And from the viewpoint of damage,the research progress of creep and fatigue of rock was emphatically presented. Besides,by referring to the research results of the creep-fatigue interaction of metal,the property,mechanism and research methods of the creep-fatigue interaction of rock were briefly discussed,which might bring forward reasonable suggestions on the research into the safety and stability of salt caverns.
