Analysis of Bridge Structure Design of Urban Rail Transit in the European Standard System—A Case Study of Egypt's 10th of Ramadan Railway Project
The 10th of Ramadan Railway Project,as Egypt's"first 27.5 KV electrified railway project under the European and American systems",is one of the state key overseas rail transit projects implemented by Chinese-funded enterprises in accordance with European and American standards and management systems in recent years.Its implementation standards,design processes and technical proposals are different from those of general urban rail transit projects in China.Therefore,based on the background of bridge structure design,this paper first analyzes the division of bridge design stages,the major difficulties of design and the corresponding solutions under the European standard system.Then,it sorts out the specifications and design criteria adopted by each bridge structure.Finally,it analyzes the design structure's design content of this project in detail,including the determination of beam type,simply supported beam structure system,prestressed box girder,bridge deck system,structural computation software and bridge aesthetics,etc.,aiming to provide some reference for the design of overseas bridges using European standards in the future.
