中文摘要：

基于12个拉拔试件的黏结试验，研究冻融循环作用对GFRP筋与混凝土之间黏绔性能的影响。拉拔试验主要包括1组未冻融的GFRP筋对比试验和3组冻融循环次数分别为50次，100次和150次的GFRP筋。试验结果表明：黏结应力随着冻融循环次数的增加而降低，但影响作用较小，故GFRP筋在冻融循环作用下与混凝土黏结性能良好。

英文摘要：

Experimental studies were performed on 12 pull -out specimens to investigate the bond behavior of GFRP rebar under freeze-thaw cycles.The test mainly contained a contrast FRRP rebar without freeze thawing and three FRRP rebars with freezing and thawing cycles for 50 times,100 times,150 times respectively.The test results show that the bond strength of GFRP rebar decreases with the increase of freeze thaw cycles,but the influence is relatively small.Therefore,the bonding performance of GFRP rebar is favorable under freezing-tha-wing actions.
