摘　　要：为了对HPF加固混凝土构件界面黏结性能进行研究,通过外包HPF加固混凝土试件的双面剪切试验,研究了修补界面所植入抗剪切销钉对界面黏结性能的影响.试验结果表明,植入销钉能够有效提高界面的黏结性能,提高试件抗剪承载力.销钉因素对界面黏结性能的灰关联分析表明,钢筋的级别对界面黏结性能的影响最大,其次是植入销钉的数量,再次是销钉的直径大小.The interfacial bonding property of concrete specimens reinforced with high performance ferrocement （HPF） was investigated through two-side shear tests, and the influence of the shear pins on the interfacial bonding property was studied. The results indicate that the pins can effectively enhance the interfacial bonding property and the shear resistance. The grey relational analysis of the influence of three factors on the bonding property shows that the most important factor is the type of steel bar, followed by the amount of pins, and, lastly, by the diameter of the pin.
