摘要: 玻璃纤维增强聚合物(GFRP)锚杆与传统钢筋锚杆相比具有优异的力学性能,有钢筋锚杆不具备的抗酸碱腐蚀性能,与其他复合材料锚杆相比,GFRP锚杆凭借自身价格低、工程性价比高等优势已在岩土锚固中崭露头角,成为钢筋锚杆的潜在替代品。本文主要介绍了GFRP锚杆在蠕变试验研究、理论分析及数值模拟等方面的研究成果。总结了GFRP锚杆蠕变力学模型和持续应力或循环荷载下的蠕变特性,归纳了GFRP锚杆蠕变性能的主要影响因素,并对GFRP锚杆长期效能以及基于试验数据进行的耐久性数值模拟分析成果进行论述。最后分析了GFRP锚杆现有蠕变性能研究中存在的不足,并对GFRP锚杆在耐久性方面以及岩土锚固领域的未来发展提出合理性建议。

Abstract: Glass fiber reinforced polymer (GFRP) anchors have excellent mechanical properties compared with traditional reinforced anchors, and have acid-base corrosion resistance that reinforced anchors do not have. Compared with other composite anchors, GFRP anchors have become a potential substitute for reinforced anchors because of their low price and high engineering cost performance ratio. This paper mainly introduces the research results of GFRP anchor in creep test, theoretical analysis and numerical simulation. The creep mechanical model and creep characteristics of GFRP anchor under continuous stress or cyclic load are summarized. The main influencing factors of creep performance of GFRP anchor are summarized. The long-term performance of GFRP anchor and the numerical simulation analysis results of durability based on experimental data are discussed. Finally, the deficiencies in the existing creep performance research of GFRP anchors are analyzed, and reasonable suggestions are put forward for the future development of GFRP anchors in terms of durability and geotechnical anchorage.

Key words: GFRP anchor, creep, durability, mechanical model, numerical simulation, composites
