临汾市乾峰大桥主桥总体设计

摘要:

乾峰大桥主桥采用跨径布置为37.5+3×65+37.5=270m的预应力砼变高连续梁,桥宽为40.5m,分幅设计,两幅之间设置20mm的离缝。在主墩处设置具有洪洞当地文化的装饰塔,整体造型优美,气势磅礴。这种采用常规连续梁桥型加装饰相结合的设计思路在满足传统桥梁设计要求的基础上,又能满足越来越高要求的景观桥梁的需要,为后续其他项目的设计提供一些经验参考。

The main pier is provided with a decorative tower with the local culture of Hongdong, which is beautiful and magnificent in overall shape. This design idea of combining conventional continuous beam bridge type with decoration can not only meet the requirements of traditional bridge design, but also meet the needs of more and more demanding landscape bridges, and provide some experience references for the design of other subsequent projects.
