摘要
介绍了千岛湖大桥主桥的墩座、V形墩斜腿、箱梁、箱梁预应力各部分的结构设计方案。通过对大桥主桥结构进行整体平面杆系有限元分析及对墩梁结合部进行空间有限元分析,验证整体结构和局部结构的受力合理性,提出了全桥施工方案,进一步确保V形墩结构的安全和质量。
This paper introduces the general situation of Qiadaohu Lake Bridge project general situation,the main bridge structure design of the bridge pier,V type pier inclined leg,box girder and box girder prestress.At the same time,the whole plane rod finite element analysis of the main bridge structure and spatial finite element analysis of pier beam connection are made in order to verify the stress of overall structure and partial structure stress rationality.Finally,the whole bridge construction plan is put forward to further ensure the safety and quality of V type pier structure.
