摘　　要：（接上期）De Lorenzis L等[7-8]又采用了一种改进的直接拉拔试件,试件形式为C形素混凝土试块,中部混凝土表层沿纵向预留方形槽。C形试块通过埋置在四角处的钢筋固定在高硬钢板上。试验中观察到4种破坏形式：①粘结剂-混凝土界面滑移破坏;②粘结剂表层劈裂破坏;In recent years,application of FRP reinforcement technique increases,mainly applied in bridge and other concrete structure reinforcement.It will become a promising technology to improve the tension and shear shortage of concrete structure,stone and wood.Effective application of FRP reinforcement technique dependents on interface properties and bond mechanisms of FRP and concrete,and effect of parameters.
