现阶段,由于现代化建设的不断推进,地上工程建设已趋于饱和,越来越多的地下工程建设开始出现,并呈持续上升的态势。然而,在地下工程建设的施工过程中,时常发生坍塌、冒顶等事故,这是因为在复杂多变的地质条件下,围岩稳定性得不到较好的保证。所以,岩土锚固是地下工程建设中必不可少的一环。本文介绍了锚固的作用方式、作用机理以及锚固系统的破坏方式,在此基础上,对现有的锚固理论和技术进行论述,并对其存在的问题加以分析,为以后该领域的研究进行一下展望。
At this stage, due to the continuous promotion of modernization, the construction of ground works has become saturated. More and more underground construction projects have started to emerge and the situation continues to rise. However, accidents such as collapse and roof fall occur frequently during the construction of underground engineering. This is because the stability of surrounding rock can not be well guaranteed due to the complex and ever-changing geological conditions. Therefore, rock and soil anchoring is an essential part of underground construction. This paper introduces the mode and mechanism of anchorage and the failure mode of anchoring system. Based on this, the existing anchoring theory and technology are discussed, and the existing problems are analyzed for future research in this field Outlook.
