摘要

为了研究混凝土和石材粘结界面的抗剪性能，设计Z型和套箍型两种试件，进行了混凝土⁃石材粘结试件界面剪切力学性能试验。试验考虑了材料强度、界面植筋情况、试件形式等变化参数。试验结果表明：界面为试件的薄弱部位，混凝土和石材的粘结界面上均发生了剪切破坏。在一定范围内，混凝土强度的提高会增强界面的剪切强度，延缓试件的开裂，减小界面同级荷载下的剪切位移；界面植筋可以显著提高试件的剪切性能，提高幅度随着植筋率的增大而增大；相同条件下，套箍型试件的剪切强度大于Z型试件，未植筋试件提高约20%，植筋试件提高约40%~55%。根据试验结果结合理论分析，提出了可考虑套箍增强作用的界面抗剪承载力计算公式。

Abstract

To investigate the shear performance of the interface between concrete and stone， the interfacial shear tests were carried out on the Z-type and hoop-type concrete-stone bonded specimens. The effects of bonding meth-ods， material strength and forms of embedded steel bars on interfacial shear properties were considered. The experimental results show that the bonding interface between concrete and stone is the weak part of the sam-ples， and shear failure occurs along the interface. Within a certain range， the increase of concrete strength will enhance the shear strength of the interface， delay the cracking of the specimens and reduce the shear displace-ment of the interface. Interfacial reinforced steel bars can significantly improve the shear resistance of the in-terface. The shear strength of the interface rises greatly with the increment of the reinforcement ratio of steel bars. The shear strength of the hoop type specimen is larger than that of the Z-type specimen， with about 20% for the unreinforced specimen and about 40% to 55% for the reinforced specimen. Based on the test results and theoretical analysis， a formula for calculating the shear capacity of the interface considering the reinforcement of the hoop was proposed.
