摘要
某高速公路高架桥跨越河流部分为单箱三室结构悬臂箱梁,半幅设分离双柱式矩形墩柱,利用既有的承台,采用钢管及悬挑支架的方式,实现了0#块浇筑施工。该方案具有工期较短、承载力好,安全系数高,同时作为悬臂梁的临时固结,为同类桥梁临时支墩设计施工提供参考。
A expressway viaduct across-river part belongs to single box three-compartment structure cantilever box girder. It sets separated double-column rectangular pier in semi-range, uses the existing cap, steel and cantilevered scaffold way to achieve 0# block placement construction. The program has a shorter duration, good carrying capacity and high safety factor. At the same time, as a temporary consolidation of the cantilever, it provides reference for design and construction of temporary piers of similar bridge.
