摘要
京沪高铁跨娄江连续梁拱桥上部结构设计为(70+136+70)m预应力混凝土连续梁与钢管混凝土拱组合结构。介绍了该桥梁上部设计结构,重点描述了拱肋安装施工技术,采用纵向滑移的方案,和梁体同步施工,节约了时间,保证了工期。
（70 ＋ 136 ＋ 70） m pre-stressed concrete continuous beam and con- crete filled steel tube arch composite structure was designed for the upper structure of continuous beam arch bridge across Lou River for Beijing-Shanghai high-speed railway. The upper structure design of the bridge was introduced, the arch rib＇in- stallation construction technology was described emphatically, time was saved and the working period was ensured by adopting scheme of longitudinal slip and simul- taneous construction of beam body.
