城市快速路桥梁预制拼装施工期间的地面道路通行效益分析

Efficiency Analysis of Ground Road Transportation during Bridge Prefabricated Construction Period for Urban Expressway

桥梁预制拼装技术相对于传统现浇法有明显优越性,能提高建设质量与速度、减小施工对环境与交通的影响。基于某预制拼装桥梁设计及施工方案,定量分析某快速路改造工程中主线桥施工期间地面道路的通行能力,并与传统现浇法指标比较。经研究发现,预制拼装施工法有更好的社会效益。

Bridge prefabricated technology is superior to cast-in-place method and that technology using in urban bridge could improve quality and speed of construction,decrease influences on environments and transportation.This paper based on design and construction schemes of bridge prefabricated,quantitatively analyzes transportation of ground road in main bridge construction for an urban expressway renovation project,and compares indexes with cast-in-place method.After research,bridge prefabricated technology has better social benefit.
