横向偏心桥墩的设计探讨

城市高架桥作为现代交通体系中的重要一环,其桥墩布置不仅要考虑桥本身,还需兼顾桥下道路净空及整体景观需求.当高架桥中心线与桥下道路分隔带中心线不重合,或桥墩布设受河道、地铁、管线等限制时,采用横向偏心桥墩是一种有效的办法.凤凰山高架桥ZX49#墩采用双层桥墩,其上层为偏心距1.55 m的横向偏心墩.介绍凤凰山高架桥ZX4...

Discussion on Design of Transverse Eccentric Pier

The pier layout of an urban viaduct as one of the important links in the modern traffic system should not only consider the bridge itself, but also take into account the road clearance under bridge and the overall landscape requirements. When the central line of viaduct is not matched with the central line of road separation belt under the bridge, or the pier layout is limited by river, subway and pipeline, the use of transverse eccentric pier is an effective method. The double-layer pier of Fenghuang Mountain Viaduct is ZX49# pier. Its upper layer is a transverse eccentric pier with eccentricity of 1.55m. By introducing the structure, analysis and calculation of ZX49 upper-layer eccentric pier of Fenghuang Mountain Viaduct, the equivalent section calculation method of special-shaped pier stud is discussed, which can provide reference for the design of similar structures at home and abroad.
