摘　　要：为了研究不同混凝土基体与植筋的粘结锚固性能,以植筋的锚固长度、植筋的锚固长度比系数等为设计参数,设计制作了14个不同混凝土基体单筋植筋试件,并进行了不同混凝土基体单筋植筋试件的拉拔试验,对不同混凝土基体与植筋的粘结锚固性能进行了分析。试验结果表明,其他条件相同,不同混凝土基体与植筋的拉拔承载力随植筋锚固长度、锚固长度比系数的增大呈线性提高。在试验结果分析的基础上,建立了不同混凝土基体植筋拉拔承载力的计算模型和计算公式,计算值与试验值符合较好,为实际工程的推广运用提供技术支撑。In order to study the bonded anchoring properties between different strength concrete base-body and planting bars, 14 different strength concrete base-body single planting bar specimens were designed and made by using the anchoring length and the anchoring length ratio coefficient of planting bar as the design parameters.The experimental results show that the pull-out bearing capacity of planting bars in different strength concrete base-body increases with the increase of anchorage length or the anchoring length ratio coefficient when other conditions are the same. Based on the analysis of the test results, the calculation model and formula of pull-out bearing capacity of different strength concrete base-body planting bar are established, and the calculated value accords with the experimental value, which can provide technical support for the popularization and application of practical engineering.
