Experimental Study and Theoretical Analysis on the Bond Behavior of Cement Grouted GFRP Bolts
Bolt is widely used in ground reinforcement engineering such as slope, tunnel or large caves engineering. The traditional steel bolt has some disadvantages, because it may be corroded by groundwater or chemical solutions, which cause the reductions of mechanical strength and service life. Glass fiber reinforced polymer (GFRP) bolt has the good characteristics of lighter weight, higher strength and corrosion-resistance. Those advantages make it a better alternative in some fields of engineering, and attract great attention of many scholars. Based on the Canadian Standards Association (CSA) criterion, pullout test is used to study the bond behaviors of GFRP bolt in cement mortar. Meanwhile, the bond stress of the GFRP bolt along the bolt longitudinal direction is analyzed in theory. The conclusions from the research may shed a light for a more rational design of GFRP anchors.
