摘要
京杭运河特大桥是宁启铁路复线电气化改造的重要节点工程,跨越京杭运河。主桥采用65 m+114 m+65 m单线预应力混凝土连续梁与钢管混凝土拱组合结构。介绍京杭运河特大桥主桥情况,着重阐述其结构构造、施工方法、考虑施工阶段的静力计算分析及受力特点,有关经验可供相关专业人员参考。
Beijing-Hangzhou Canal Super-long Bridge is an important node project spanning Beijing-Hangzhou Canal of the double-track electrification reconstruction of Ningqi Railway.The main bridge is the structure combined of 65 m+114 m+65 m single-track pre-stressed concrete continuous girder with concrete filled steel tube arch.The article introduces the main bridge of Beijing-Hangzhou Canal Super-long Bridge,and focuses setting-forth on its structural construction,construction method,static calculation analysis and stress characteristic of construction period.The relative experience can be referred for the relative technical members.
