南通深南路大桥工程总体设计研究

Research on the Overall Design of Nantong Shennan Road Bridge Project

南通深南路大桥工程跨越的九圩港航道等级高,距离两岸道路近,如何进行合理的的设计满足与两岸道路顺接的功能,是该项目总体设计的关键。文章从桥型选择、主桥构件设计、引桥结构设计、主墩防撞设计等方面进行详细的总体设计,并根据总体设计方案,提出边跨支架拼装、主跨大节段浮运吊装对航道影响较小的施工方案,以期为类似桥梁项目提供参考及理论指导。

The Nantong Shennan Road Bridge project crosses Jiuwei Port channel which is of high grade and close to the roads on both sides.How to carry out reasonable design to meet the function of connecting the roads on both sides is the key to the overall design of the project.This paper makes a detailed overall design from the aspects of bridge type selection,main bridge component design,approach bridge structure design and main pier anti-collision design.According to the overall design scheme,the construction scheme of side-span bracket assembly and floating hoisting of large segments of the main span is proposed,which has little influence on the channel,so as to provide reference and theoretical guidance for similar bridge projects.
