Abstract: In view of the factors influencing FRP Bolt anchoring force including anchorage length，anchoring time，anchoring material，FRP Bolt pullout tests are carried out in the laboratory.By contrasting on the single factor，the impacting law of anchorage length，anchorage time，anchorage material on the anchorage force are analyzed.It is concluded that the FRP Bolt anchoring force increases with increasing of anchoring length and anchoring time.Various factors should be fully taken into considerations for selecting the anchoring materials.It plays an important rule in the design of the supporting parameters and the analysis of supporting mechanism of FRP bolt.

Key words: FRP bolt, Anchorage force, Test analysis, Influencing factors, Pulling force
