摘要
泉州市站前大桥为2跨变截面预应力混凝土连续刚构桥,采用悬臂浇筑法施工。介绍了站前大桥的设计技术标准、外形及预应力构造,简述了悬臂浇筑施工分段情况。重点介绍了主桥工程构造的正截面承载能力、长期荷载组合下正截面应力分析和持久状况下正常使用极限状态结构挠度分析等静力计算分析。简单介绍了对桥梁的抗震分析和稳定分析结果。
Zhanqian Bridge in Quanzhou is a prestressed concrete continuous rigid frame bridge with two-span & variable cross-section by adopting the cantilever pouring method.Several key elements of the bridge are introduced such as the design technology standard,the appearance & the prestress structure,and the section construction of cantilever pouring.And some static force calculation analyses are presented including the normal section bearing capacity of the main bridge,the normal section stress analysis of long-term combination and the limit states structural deflection analysis under lasting condition.Finally,the anti-seismic analysis and the stable analysis results are also mentioned briefly.
