玻璃纤维增强聚合物锚杆研究进展

CURRENT STATUS AND PROSPECTS OF GFRP ANCHOR RESEARCH

岩土锚固是土木工程中一个非常重要的领域,锚杆作为其核心结构,受到了极大的关注。玻璃纤维增强聚合物(GFRP)锚杆与传统钢筋锚杆相比,具有更加出色的抗拉强度、不易锈蚀和介电性好等优点,在一定程度上能够节约工程成本,在越来越多的工程中得到了应用。本文对GFRP锚杆的发展历史、力学性能及耐久性等相关研究进程进行梳理和总结,讨论了GFRP锚杆研究和应用中存在的不足,并对GFRP锚杆未来的发展提出建议。

Anchor anchoring is a very important field in civil engineering, and the bolt is greatly concerned as its core structure. Compared with traditional steel anchors, glass fiber reinforced polymer (GFRP) anchors have better tensile strength and are less prone to be rusted, which can reduce engineering costs to a certain extent and is used in more and more projects. In this paper, the development history of GFRP anchors and the research progress of mechanical properties are briefly introduced. The shortcomings in the research of GFRP anchors are discussed, and the future development of GFRP anchors is proposed.
