| 摘 要： | 通过在混凝土中植筋的正交试验研究，得出植筋深度、混凝土强度、钢筋直径三因素在植筋中由主至次的重要性次序是：钢筋直径→植筋深度→混凝土强度；并探讨了三因素对植筋强度的影响及其不同试验条件下在拉应力作用下植筋的破坏形态；还根据试验结果分析给出植筋技术工程应用中的指导性建议。

| Abstract: | The conclusion of the important order of the factor among the depth of the embedded steel bars,the strength of the concrete, the diameter of the reinforcing bar was obtained.The first important order is the diameter of the reinforcing bar ,next is the depth of the embedded steel bar,and the third is the strength of the concrete.The influence of the three factors to the strength of the embedded steel bar and destroy form of embedded steel bar after the function of pull out stress in different condition of the experiment was also discussed.Some guide suggestions of the embedded steel bars in engineering appfication were given to in this paper after the analysis of the experiment result. |
