摘　　要：无伸缩缝桥梁和有伸缩缝桥梁的主要区别在于主梁与桥台的连结方式不同,并由此影响结构的受力性能。本文根据工程实际的需要,提出两种新的无伸缩缝桥梁桥台与主梁结点的构造方式,并结合两种常用的结点构造,较详细地介绍这四种结点构造的受力特点和在实际工程中的施工顺序,以促进无伸缩缝桥梁在实际工程中的应用和发展。The jointless bridge distinguishes the common ones from the connections between the abutment and the main beam, which affects the load property of the structures. In the paper, two types of crunode structures are brought forward, and two traditional crunode structures are introduced. Then their factures and construction sequences are described in detail. The research promotes to the jointless bridge in the engineering.
