通过文献查阅与分析,从锚杆结构、锚杆材料两方面综合介绍了新型锚杆的研究进展,并与传统锚杆相比较,分析了新型锚杆的锚固特点及其在不同工程地质条件下的适用性。例如,矿山巷道工程中宜使用让压锚杆及柔性注压锚杆,土遗址加固工程中宜使用竹筋复合锚杆,大跨度地下硐室中宜使用MFRP锚杆,对建设红线有要求的城市岩土工程中宜使用可回收锚杆,软土地基的抗浮设计宜使用充气锚杆。在此基础上,总结了新型锚杆发展中仍存在的一些问题,并探讨了今后需要进一步开展的研究工作。
Through literature review and analysis, the research progress of the new type of anchor is introduced from the aspects of the structure of the anchor and the material of the anchor. Compared with the traditional anchor, the characteristics of the new type of anchor are analyzed and analyzed under different engineering geological conditions Applicability. For example, mine tunnel engineering should be used to allow the pressure anchor and flexible injection anchor, soil reinforcement project should be used in bamboo reinforcement composite anchor, long-span underground chamber should use MFRP anchor, the construction of the red line requirements Should be used in urban geotechnical reusable anchor, anti-floating design of soft ground should use inflatable anchor. On this basis, some problems that still exist in the development of the new type of anchor are summarized and the research work that needs to be further carried out in the future is discussed.
