摘　　要：通过在不同强度混凝土中植入不同型号角钢的静力拉拔试验,得出了植钢的3种破坏模式、荷载滑移全过程曲线、荷载应变实测曲线。与传统的植筋试验结果相比,植钢技术更易充分发挥整个锚固段粘结力的作用。植钢与植筋的静力拉拔试验得到的破坏模式及荷载滑移全过程曲线有较大区别,对此进行了详细分析,并提出了植钢技术和植筋技术的应用前景。In this paper, though the pull-out tests of adhesive steel in concrete,three destroy forms,the whole load-slid curves,the load strain measured curves of different style angle steel with different grade concrete were obtained. Compared with traditional planting bar test result,it was found that the embedded steel in concrete should give more fully play to the adhesive force than the embedded bar. There were also some differences with the failure modes and the whole load-slid curves. The appli-cation prospects of two kinds of anchor technologies, i.e. embedded steel technology and embedded bar technology, were proposed.
