摘　　要：通过对粘结型锚具的分析,总结出粘结型锚具更适用于FRP筋的锚固。鉴于此,提出了一种新型先张法夹具,开展了预应力BFRP筋夹具锚固性能研究,发现高强灌浆料-半灌浆套筒粘接式锚具能够对预应力FRP筋实现较为快速、稳定的锚固。Through the analysis of bonded anchorage,it is concluded that bonded anchorage is more suitable for the anchorage of FRP bars.In view of this,a new type of pretensioning fixture is proposed in this paper,and the anchoring performance of prestressed BFRP bars is studied.The pioneering proposed high-strength grout and semi-grout sleeve bonding anchorage can achieve rapid and stable anchoring of prestressed FRP bars.
