摘　　要：探讨了不同的影响因素,如型钢与混凝土的锚固长度、混凝土的强度等对型钢混凝土组合结构的粘结滑移性能的影响。试验结果显示,这些因素对组合结构的粘合结构强度和滑移特性有显著的影响;锚固长度和混凝土强度与组合结构的初始粘合结构、极限粘合结构呈正相关关系;膨胀剂掺量影响了混凝土强度,进而影响了组合结构的粘合结构性能。研究结果对于深入理解型钢混凝土组合结构的受力机理和工作特性具有重要意义,为型钢混凝土的设计、施工提供了借鉴。The influence of different influencing factors,such as the anchorage length of steel and concrete,and the strength of concrete,on the bond-slip properties of steel and concrete composite structures were discussed.The test results showed that these factors had significant effects on the bond strength and slip characteristics of the composite structure.The anchorage length and concrete strength were positively correlated with the initial and ultimate bonded structures of the composite structure.The dosage of expansion agent affected the strength of concrete,which in turn affects the bonding performance of composite structures.The research results are of great significance for in-depth understanding of the mechanical mechanism and working characteristics of reinforced concrete composite structures,and provide a reference for the design and construction of reinforced concrete.
