随着经济的不断增长和国家发展的需要,在沿海地区和跨海峡地区,急需建设跨越能力更大的超大跨径悬索桥工程。以琼州海峡跨海工程,主跨3 000m双塔悬索桥原型设计方案为背景,针对建设规模宏大、建设条件复杂,风大、浪高、水深(45~80m)等严峻的建设条件,对3 000m级超大跨径悬索桥上部结构的施工技术、施工装备等方面进行了系统研究工作,为跨海峡桥梁建设提供有力的技术支撑。
With the continuous economic growth and the needs of national development, it is urgent to build a large-span suspension bridge project with greater capacity in the coastal areas and across the Strait. Taking the Qiongzhou Strait Cross-sea Project and the main span 3 000m twin tower suspension bridge prototype design scheme as the background, aiming at the severe construction conditions such as large-scale construction, complicated construction conditions, windy, wave height and water depth (45 ~ 80m) Level super-long-span suspension bridge superstructure construction technology, construction equipment and other aspects of the system research work for the cross-strait bridge construction to provide a strong technical support.
