To solve the problem of reinforcement bolt corrosion caused by the safe stability problem in geotechnical engineering, and engineering red line in geotechnical engineering, the fiber-reinforced composite material is gradually applied to the civil engineering field, and glass fiber reinforced polymer has high strength, light quality, corrosion resistance, the advantages of easy cutting has been widely used. In this paper, the stress distribution and deformation characteristics of GFRP anchors in the process of pipe pulling are studied through the excavation tube pulling test of GFRP anchors in actual working conditions. Secondly, the performance difference between the GFRP bolt and reinforced bolt in foundation pit engineering is analyzed. The results show that the axial force of the GFRP anchor bolt decays fastest near the anchor head, and decreases with the increase of anchor depth The shear stress distribution is convex. With the increase of the drawing load, the shear stress peak will increase, and the influence range of the shear stress will also increase. With the increase of the load, the shear stress peak of the GFRP bolt and the anchor solid will shift to the position far away from the anchor head.
