摘　　要：预制预应力混凝土结构兼有预制混凝土结构和预应力混凝土结构的特点,在建筑和基础设施领域中具有良好的应用前景。系统总结了包括本课题组在内的国内外研究团队关于预制预应力混凝土框架、剪力墙和综合管廊结构受力性能的研究进展,研究对象主要包括预制预应力混凝土框架结构(预制节点核心区和现浇节点核心区两类)、预制预应力混凝土剪力墙结构和预制预应力混凝土综合管廊结构。已有研究表明:上述三种预制预应力混凝土结构均具有良好的承载力和变形恢复能力;采用现浇节点核心区的框架结构总体抗震性能“等同现浇”,而相比之下,采用预制节点核心区的预制预应力混凝土框架结构则具有典型的半刚性特征,延性和耗能稍差;预制预应力混凝土剪力墙结构在地震作用下的变形以刚体转动为主,墙体自身损伤和残余变形均较小,延性和耗能较差;预制预应力混凝土综合管廊整体结构具有良好的防水性能、较高的承载力与变形恢复能力。此外,还介绍了上述三种预制预应力混凝土结构的工程应用和技术标准现状。最后,对预制预应力混凝土结构的研究方向进行了展望。Precast prestressed concrete structures,possessing the characteristics of both precast concrete structures and prestressed concrete structures,exhibit promising application prospects in the fields of construction and infrastructure.The paper systematically summarized the research progress made by domestic and international research teams,including the authors’group,on the mechanical properties of precast prestressed concrete frames,shear walls,and utility tunnel structures.The research objects primarily encompassed two types of precast prestressed concrete frame structures(with precast and cast-in-situ joint cores),precast prestressed concrete shear wall structures,and precast prestressed concrete utility tunnel structures.Existing research indicates that all three structures possessed excellent bearing capacity and deformation recovery capability.Precast prestressed concrete frame structures with precast joint cores exhibited limited ductility and energy dissipation capability,displaying typical semi-rigid characteristics,while those with cast-in-situ joint cores demonstrated good seismic performance.Precast prestressed concrete shear wall structures primarily underwent rigid body rotation during seismic events,with no significant damage or residual deformation to the main wall body,but their ductility and energy dissipation capacity were unsatisfactory.Precast prestressed concrete utility tunnel structures demonstrated good waterproof performance,high bearing capacity and recovery capability.Furthermore,the applications and codes for these three types of structures were summarized.Finally,the research prospects for precast prestressed concrete structures were discussed.
