机场快速路高架桥现浇箱梁支架设计与施工

DESIGN AND CONSTRUCTION OF CAST IN SITU BOX GIRDER SUPPORTS FOR AIRPORT EXPRESSWAY VIADUCT

基于飞机的特性,通常机场都建立在远离城镇人口的边缘地带,而为了保证交通便利性和快捷性,修建机场快速路成为常见工程,在工程建设中考虑需求和原有建筑限制等因素,高架桥极为常见,在桥梁建筑中箱梁凭借操作简便、耗时短等深受青睐,目前机场快速路高架桥建设中常将现浇箱梁作为首选。在此以溪东路(翔安南路-机场快速路段)为例,阐述机场快速路高架桥现浇箱梁支架设计及施工要点,以期本文研究内容,为我国同类型工程提供更多借鉴。

Based on the characteristics of aircraft,airports are usually built in marginal areas far away from urban population.In order to ensure traffic convenience and rapidity,the construction of airport expressways has become a common project.Factors such as demand and original building restrictions are considered in the project construction.Viaducts are very common.In bridge construction,box girders are favored by virtue of simple operation and short time consumption,At present,cast-in-situ box girder is often used as the first choice in the construction of airport expressway viaducts.Taking Xidong Road(Xiang’an South Road Airport Expressway Section)as an example,this paper expounds the design and construction points of cast-in-place box girder support of airport expressway viaduct,with a view to providing more reference for similar projects in China.
