摘要：超高性能混凝土（UHPC）凭借超高强度、超高韧性、超高耐久性能等优点已经在装配式结构中得到广泛应用。UHPC与普通混凝土（NC）结合面的粘结性能成为制约装配式结构整体性能的关键因素，结合国内外UHPC-NC结合面粘结性能的研究结果，聚焦于结合面粘结性能的影响因素、微细观粘结机理、宏观力学性能和耐久性能等关键点，综述UHPC-NC结合面粘结性能的研究进展，为UHPC湿接缝应用在装配式普通混凝土构件中提供参考。

Abstract：As a kind of ultra-high performance concrete material，UHPC has been more and more widely used in assembled structures by virtue of the characteristics of ultra-high strength，high durability，high ductility and so on. The bonding performance of UHPC and NC joint surface becomes the key factor restricting the overall performance of fabricated structures. Based on the research results of bonding performance of UHPC-NC interface at home and abroad，focusing on the key points such as influencing factors of bonding performance，micro and micro bonding mechanism，macro mechanical properties and durability，the research progress of bonding performance of UHPC-NC interface is summarized，which provides a reference for the application of UHPC wet joint in fabricated common concrete members.
