摘　　要：为了研究GFRP直径、橡胶取代率及立方体抗压强度对GFRP筋橡胶混凝土粘结性能的影响,按照CSA标准设计了15组标准粘结试件。抗拔试验结果表明:拉拔试件的破坏形态大多为拔出破坏;GFRP直径、橡胶取代率及立方体抗压强度对粘结强度均有影响,其中粘结强度随GFRP筋直径的增大而下降,随橡胶取代率的增加而下降,随立方体抗压强度的增加而提高。Based on the pull-out tests of 15 groups specimens according to CSA standard, the influence of the diameter of GFRP rebars, the incorporation rate of rubber and cubic compressive strength on bond behavior of GFRP rebars and rubberized concrete were studied. The test results show that the failure mode of mostly specimens are pull-out failure; the diameter of GFRP rebars, the incorporation rate of rubber and cubic compressive strength all have influences on the bond behavior of GFRP-rubberized concrete, and the bond performance decreases with the increase of the diameter of GFRP rebars and the incorporation rate of rubber, and increase with the cubic compres- sive strength of the increase of GFRP-rubberized concrete.
