| 摘 要： | 为了深入研究GFRP锚杆的锚固机理,模拟实际情况制作了试验模型,进行了拉拔试验.通过对实验结果的分析和研究,获得了砂浆粘结GFRP锚杆在拉拔条件下沿杆体的轴力和剪应力分布规律以及随荷载增大的演化过程,对荷载传递的机理进行了讨论,可为同类研究参考.

| Abstract: | In order to study the GFRP bolt's anchoring mechanism deeply,the experiment model is manufactured by simulating the fact circs,and the drawing test under the jack load is carried out.Based on researching and analyzing the experimental result,regularities of distribution of axial force and shear stress of the mortar bond GFRP bolt,and the evolutionary with the increase of load are obtained,the theory of load transfer mechanism is discussed.It is a reference for the similar research. |
