| 中文摘要: |
| 独塔无背索弯坡斜拉桥的结构受力复杂,在施工中主梁的施工方案对整个桥梁的建造起到关键作用.根据孝襄高速公路孝南互通匝道独塔无背索弯坡斜拉桥的主粱设计特点,采用塔梁同步施工的方案,对梁体架设详细方法和施工中的关键因素做了分析研究.该桥梁体架设中各项指标符合要求,节约了施工成本,也缩短了施工工期. |
| 英文摘要: |
| Because of the complex structure stress condition of single tower cable-stayed curve bridge without back cable,the girder construction scheme plays a key role in total bridge construction. According to the design characteristic of the girder of single tower cable-stayed curve bridge without back cable at Xiaonan interchange in Xiaoxiang highway, girders are constructed by the synchronous-cross technique. The detail girder construction method and the key factors are studied. Every construction index is satis... |
