【摘要】 在绿色低碳发展理念的倡导下，桥梁预制拼装技术在城市桥梁建设中的应用越来越广泛。依托上海两港大道预制拼装桥梁实际工程，其预制立柱钢筋与盖梁采用灌浆波纹钢管锚固连接。为验证贴边埋置灌浆波纹钢管锚固连接能提供可靠的黏结锚固能力，考虑不同钢筋锚固长度、灌浆与压浆工艺等因素，开展灌浆波纹钢管-钢筋黏结滑移力学行为的拉拔试验研究，研究损伤发展过程、破坏模式、力与位移曲线等力学行为，并进行归纳总结，为实际工程的应用提供技术支撑。更多还原

【Abstract】 Under the advocacy of the concept of green and low-carbon development, the application of bridge prefabrication and assembly technology is more and more extensive in urban bridge construction.Relying on the practical project of prefabrication assembly bridge of Shanghai Lianggang Avenue, the precast column rebar is anchored and connected with the grout corrugated steel pipe. In order to verify that the anchorage and connection of embedded grout corrugated steel pipe on edge can provide the reliable bonding and anchoring ability, by considering the different reinforcement anchorage lengths,pouring, grouting and other technical factors, the pullout test research on the bonding and slipping mechanical behavior of grout corrugated steel pipe and rebar is carried out to study and summarize the mechanical behaviors such as damage development process, failure mode, force and displacement curve,which provide the technical support for the application of practical projects.更多还原
