摘　　要：玻璃纤维增强塑料土钉是近年来出现的一种新型的边坡支护结构体,具有自重轻、强度高、耐腐蚀等优点。从玻璃纤维增强塑料土钉的基本特性出发,综述了该类土钉对边坡的支护机理的国内外研究现状,比较了传统钢筋土钉和玻璃纤维增强塑料土钉的优、缺点,并探讨了玻璃纤维增强塑料土钉与土体界面间的力学传递机理,提出了今后的研究思路。The glass fiber reinforced polymer（GFRP） soil nail is a newly developed structural element for slope stabilization and has the advantages of light dead weight,high strength and high resistance to corrosion,etc.In this paper,based on the basic characteristics of GFRP soil nail,the current research progress on the supporting mechanism of GFRP soil nail for slope was summarized.The merits and demerits of conventional steel soil nail and GFRP soil nail were compared and the mechanical transfer mechanism on the interface between the GFRP soil nail and soil mass was analyzed.The suggestions for further research were briefly presented.
