摘　　要：对108根钢筋进行了混凝土无机胶植筋拉拔试验。研究了无机胶作用下的植筋锚固性能。采用双因素方差分析法对植入钢筋的直径大小及锚固深度对植筋的极限拉拔力的影响程度进行显著性检验。根据试验数据拟合出三者间的关系式,为设计提供参考。This paper reports the experimental results of 108 inorganic adhesive steel bars in concrete under tensile load. The anchorage behavior is investigated. Using two factors analysis of variance to carry on significance examination to the influence degree of the diameter and anchorage depth, which made on the ultimate anchorage strength. According to the experimental data, the relationship between the diameter, the anchorage depth and the ultimate anchorage strength is drew up, which provide a reference for the design.
