摘　　要：在我国现代桥梁发展中,连续刚构桥属于是一个重要型式,其结合了T形刚构、连续梁的优点,受力明确,适应大跨度桥梁发展的需要。基于此,首先,分析了大跨径预应力连续刚构桥优越性。接着,从悬臂施工角度论述了大跨径预应力连续刚构桥施工技术;最后,以五河淮河特大桥工程为例,具体探讨了大跨径预应力连续刚构桥挂篮悬臂浇筑施工与控制要点,以期为类似工程提供参考,推动我国桥梁施工技术发展。The continuous rigid-frame bridge is an importance type in the modern bridge development of China. Combined with the advantages of T-type rigid frame and continuous girder, its stress is clear and it is adapted to the development demand of long-span bridges. Based on this, the article firstly analyzes the advantages of long-span pre-stressed continuous rigid-frame bridge, then discusses its construction technology from the angle of cantilever construction, and finally further discusses the construction and control essentials of long-span pre-stressed continuous rigid-frame bridge by the form traveler cast-in-cantilever method of Wuhe Huaihe River Bridge in order to provide the reference for the similar projects and to promote the construction technology development of bridges in China.
