摘　　要：通过正交试验研究在不同强度的混凝土中植入不同型号的角钢,得出角钢型号、植钢深度、混凝土强度在植钢中对锚固强度的影响,其由主至次的次序为:角钢型号→植钢深度→混凝土强度。分析了三因素对植钢强度的影响以及不同试验条件下拉应力作用对植钢的破坏模式,并与传统的加固方法——植筋加固法进行比较,得出植钢加固法较植筋加固法应用更为广阔。The conclusion of the important order of the factor among the Section steel Model of the reinforcing L-bar, the strength of the concrete,the depth of the embedded steel L-bar was obtained. The first important order is the Section steel Model of the reinforcing L-bar, next is the depth of the embeded steel L- bar, and the third is the strength of the concrete. The influence of the three factors to the strength of the embeded steel L-bar and destroy form of the embeded steel L-bar after the function of pull out stress in different condition of experiment was also discussed. And was compared with the traditional method of the embeded steel bar in the concrete. The embeded steel L-bar technology have broader application was obtained.
