摘　　要：随着我国经济建设的快速发展,以及混凝土浇筑工法、预应力技术等桥梁施工技术的不断改进,带来了我国桥梁事业的蓬勃发展,其中预应力混凝土连续梁桥是桥梁中广泛应用的一种桥型。满堂支架现浇法、悬臂施工法、简支变连续施工法、逐孔施工法以及顶推施工法是现有的连续梁桥常用的施工方法。不同的施工方法会对连续梁桥的内力、线形产生不同的效应,特别是大跨度预应力混凝土连续梁桥,其结构受力特点比较复杂。With the rapid development of economic construction in China,as well as the continuous improvement of bridge construction techniques,such as concrete placing method and prestressing technology,the bridge undertaking in China is booming,in which the prestressing concrete continuous beam bridge is a bridge type widely used in bridges.There are many construction methods for continuous beam bridge,such as full support method,cantilever construction method,simple supporting to continuous method,hole-by-hole construction method and incremental launching method.The internal force and alignment of continuous girder bridge are closely related to its construction method and construction process.Especially for large-span pre-stressed concrete continuous girder bridge,the structural stress characteristics are complicated.
