摘　　要：根据混凝土植筋拉拔试验的试验设计以及试验的实施过程，研究了混凝土植单锚、群锚在拉拔力作用下的破坏形态，并对单锚效应、群锚组合效应对混凝土植筋极限承载力的影响进行了研究。结果显示随着锚筋数目的增加，群锚效应越显著，锚栓的承载力有一定的提高。According to the pull - out tests design of planting bars in concrete and the implementation process of tests, the paper studied the failure mode of the single anchor and the anchor group by drawing force. Then it analyzed the influence of single anchoring effect and group anchoring combination effect on the ultimate bearing capacity of planting bars in concrete. The results show that group anchoring combination effect is more pronounced and the bearing capacity of the anchor can be improved with the increase of the number of anchor bars.
