Study On Construction Method Of Large-scale Concrete-filled Steel Tube Arch Bridges

The increase of span length of concrete-filled steel tube arch bridge promoting the development of bridge structure analysis and design theory and construction technology.According to historical experience and development of the Chinese concrete-filled steel tube arch bridge,it is not difficult to find some problems which are currently exist and need to be resolved.Such as the lack of construction specification of concrete-filled steel tubular arch bridge and the phenomenon of concrete loss of arch-back,etc.In order to make the concrete-filled steel tube arch bridge continuously maintain the leading level around the world and ensure the quality of construction,the effective construction management method is an essential step to promote better and faster development of concrete-filled steel tube arch bridge.This thesis taking Hong xing road across Fu He bridge as the engineering background.According to the key links,key processes and new technology of the bridge construction,in strict accordance with the schedule,quality,safety and other targets of contract for construction preparation of construction design documents to ensure that the requirements of the contract are guaranteed.And it discusses the construction scheme,method and technical measures.Then the thesis makes a detailed introduction about the construction schedule.Finally,the thesis introduce the measures which are in order to ensure the engineering quality,occupational health and safety and the reasonable material supply.The study in this thesis can provide the reference in the future for the concrete-filled steel tube arch bridge construction.
