摘　　要：对26个不同埋深、不同直径和不同砂浆强度的GFRP筋与砂浆拉拔试件进行了拉拔承载力以及粘结强度的研究。结果表明,拉拔承载力随着埋深的增加而增大,随着砂浆强度的增大而增大,但随着直径大小的变化不明显;粘结强度随着拉拔试件的埋深的增大而减小,随着直径的增大而减小,随着砂浆强度的增加而增大。利用ANSYS程序对GFRP筋与砂浆拉拔试件进行了仿真分析,结果表明,模拟结果与试验结果较为接近,即利用ANSYS软件能够较为准确用来验证试验结果。The pull-out bearing capacity and bond strength based on 26 GFRP bars and mortar pull-out specimens are experimentaly studied with different buried depth,different diameters and different mortar strength.The experimental results illustrate that pull-out bearing capacity increases with increasing depth,increases with increasing strength of mortar,but it is not obvious with the change of the diameter.For bond strength,it decreases with the pull-out specimen depth increasing,decreases with the diameter increasing,but it increases with increasing strength of mortar.The ANSYS program is used to simulated GFRP bars and mortar pull-out specimens.The results show that the simulation results are similar with the experiment results,which means it can verify the test results accurately by using ANSYS software.
