摘要
该桥为双塔组合梁自锚式悬索桥,主桥跨径布置采用150 m+370 m+150 m=670 m。依据相关技术标准及工程条件,介绍了桥墩、承台、桩基设计及计算分析,并对所采用的主桥基础施工方案进行了要点分析。综合考虑了受力,以及整体和通航要求,经分析和计算,最终形成一个安全适用、结构合理的设计形式,以供类似工程参考借鉴。
This bridge is a double-pylon self-anchored suspension bridge. The span layout of the main bridge is 150 m+370 m+150 m=670 m. On the basis of the relative technical standards and engineering conditions, the design, calculation and analysis of pier, base slab and pile foundation are introduced. And the essentials adopted in the foundation construction scheme of the main bridge are analyzed. The stress,the entirety and the navigation requirements are comprehensively considered. After analysis and calculation, a safe and applicable design form with reasonable structure is finally formed in order to provide the reference for the similar projects.
