城市高架桥梁拼宽方案比选

针对某高架拓宽工程提出了四种桥梁拼宽改造方案。建立工程项目三维空间模型,经过对结构性能、桥梁景观、施工对交通的影响、工程造价等多方面的分析比选,推荐利用老桥桥墩加建钢盖梁的方案。经计算分析,推荐方案承载能力和使用性能均能满足规范要求,具备可行性,可为相关工程提供借鉴和参考。

Comparison of Widening Scheme for Urban Elevated Bridge

Aiming at a viaduct widening project,four kinds of bridge widening reconstruction schemes are put forward.A 3D spatial model is established for the engineering project.By analyzing and comparing many aspects of structural performance,bridge landscape,construction impact on traffic and engineering cost,the scheme of constructing the steel bent cap on the old bridge pier is recommended.Through calculation and analysis,the bearing capacity and service character of the recommended scheme can meet the standard requirements and are feasible,which can provide reference for the related projects.
