Cost Reduction of Construction of Bridges for the High-Speed EMU

동력분산형 고속철도의 교량형식에 따른 교량건설비용 저감방안 연구

The railway bridge design specification used in our country at present, is reflected results that take into account link between vehicle and roadbed according to decision of TGV vehicle style in 1994, and executes design verification. Hereafter, the particular loading condition and the design speed of the high-speed EMU that is recognized to the next generation of high speed railway, are plain difference with TGV vehicle style decided in 1994. The effect that these load and design speed get in roadbed, especially superstructure, displays difference with the existent high speed railway. The goal of this study is to choose the suitable bridge type, and to reduce the construction cost for the next generation of railway, i.e., the high-speed EMU.
