摘要/Abstract

摘要： 为探究钢绞线网增强ECC与混凝土的界面黏结性能,以混凝土强度、界面黏结长度和黏结宽度为试验参数,对设计制作的7组21个梁式试件进行界面黏结性能试验.结果表明:在人工凿毛界面处理方式下,试件产生界面剥离和钢绞线断裂两种破坏形态;界面剥离承载力随着混凝土强度的提高而增大;在有效黏结长度范围内,界面剥离承载力随着黏结长度的增大而增大,而对界面黏结强度无明显影响;界面黏结宽度对界面剥离承载力无显著影响,但界面黏结强度随之减小.在有效黏结长度试验统计分析的基础上,建立了钢绞线网增强ECC与混凝土的界面剥离承载力预测模型,验证分析表明该预测公式具有较好的适用性.

Abstract: In order to explore the interface bonding performance of steel wire mesh reinforced ECC and concrete, the interfacial bonding performance of a total of 21 beam specimens designed and manufactured by 7 groups were tested with concrete strength, interface bonding length and bond width as test parameters. The results show that there are two failure modes: interface stripping and strand rupture. The interface peeling capacity increases with the increase of concrete strength. In the range of effective bonding length, the interface stripping capacity increases with the increase of bonding length, but has no obvious effect on the interface bonding strength. The bonding width of the interface has no significant effect on the tensile strength of the interface, but the bonding strength decreases. Based on the statistical analysis of effective bonding length test, the prediction model of the interface stripping capacity between steel wire mesh reinforced ECC and concrete was established, and the verification analysis showed that the prediction formula had good applicability.
