预应力混凝土连续梁桥以结构受力性能好、变形小、伸缩缝少、行车平顺舒适、造型简洁美观、养护工程量小、抗震能力强等特点而成为最富有竞争力的主要桥梁之一。随着预应力技术的发展和不断完善,尤其是悬臂、顶推等施工方法的出现,预应力混凝土连续梁桥如虎添翼,无论是城市桥梁、高架道路、山区高架栈桥,还是跨越江河湖海的大桥,预应力混凝土连续梁桥以独特的魅力而取代其他桥梁,成为优选方案。另外,从国内已建成的钢桥、钢筋混凝土及预应力连续梁桥的数量来看,预应力混凝土连续梁桥已远远超过半数,充分表现出预应力混凝土连续梁桥的强大生命力。
The prestressed concrete continuous girder bridge is one of the most competitive bridges with good mechanical performance, small deformation, few expansion joints, smooth and comfortable driving, simple and beautiful appearance, small maintenance projects and strong anti-seismic capacity. With the development and continuous improvement of prestressing technology, especially the emergence of construction methods such as cantilevering and jacking, prestressed concrete continuous girder bridges become more powerful. Whether it is urban bridges, viaducts, elevated viaducts, or bridges across rivers, lakes and seas , Prestressed concrete continuous girder bridge with a unique charm to replace other bridges, a program of choice. In addition, from the number of steel bridges, reinforced concrete and prestressed continuous girder bridges built in China, the prestressed concrete continuous girder bridges have far exceeded half and fully demonstrate the strong vitality of prestressed concrete continuous girder bridges.
