福州三环路淮安大桥桥型方案及关键技术研究

Bridge Type Scheme & Key Technology Research on Huai’an Bridge of Third-Ring Rd. in Fuzhou

淮安大桥为福州三环路跨闽江北港的关键工程。该桥位于河道急弯段,水文及通航条件不理想,且桥位受规划和用地条件限定。通过桥梁跨径布置和桥型方案的选择来避免各种不利因素,并在关键技术上进行优化,以达到良好的经济技术指标和社会效果,是该桥设计中最重要的课题。

Huai'an Bridge is a key project of Fuzhou Third-Ring Rd. across the North Port of Min River. The bridge is located in the sharp bend section of the river. The hydrological and navigable conditions are not ideal, and the location of the bridge is limited by the planning & land use conditions. The most important task in the design of the bridge is to avoid all kinds of unfavorable factors through the selection of bridge span layout & bridge type scheme, and optimize the key technologies to achieve good economic, technical indicators & social effects.
