摘要
随着煤炭开采深度的逐步增加和水电工程、交通工程的大规模建设,复杂条件下的岩体工程越来越多,岩体锚固理论与技术遇到了极大的挑战,出现了许多问题。首先,回顾了岩体锚固技术产生、发展的历程,从锚固提高岩体整体物理力学性能方面,介绍了岩体锚固机理研究的进展情况;其次,详细讨论了锚固界面失效形式及界面应力传递的相关理论;最后,指出考虑时间效应的锚固流变机理应是今后深部岩体工程研究的重点方向。
With the gradual increase of mining depth and the large-scale construction of hydropower projects and traffic engineering,and the complex rock engineering becoming more and more existed,the theories and technologies of rock mass anchorage met with enormous challenges and many problems occurred.Firstly,the occurrence and development process of rock mass anchorage were reviewed and several achievements in study of rock mass anchorage mechanism were introduced from the aspect of the whole physical-mechanical properties improved by the anchoring of rock mass.Several typical theories on failure of interface patterns and the related theories of interface stress transmission were discussed in detail.Finally,the paper pointed out that anchorage rheology mechanism considering time effect should be the important research thrust of rock mass engineering in future in deep mines.
