摘要
岩石破裂后会发生体积膨胀且仍具有一定的承载能力,煤矿中多利用岩石的该性质进行支护。作者从研究岩石峰后特性的重要工程意义着手,叙述了岩石峰后剪胀的概念、发展历史和研究现状,以及目前研究中存在的问题,强调了研究岩石峰后剪胀效应的重要性。
Rock mass dilates at its post-failure stage and it still has carrying capacity to a certain extent.These characteristics always react on tunnel supports.Beginning with the important engineering significance of the rock post-failure behavior,this paper depicts the concept of rock dilatancy nature,its development and research actuality.The problems exist in actual researches are also noticed in this paper,and the importance of research on rock post-failure behavior are emphasized at last.
