Abstract

Beijing-Tianjin inter-city railway is the first built passenger dedicated line with the speed of 350 km/h in our country. During the design, new ideas of bridge construction were carried out in order to ensure the safety, amenity and stability requirements of the train under high-speed condition. At the same time, concepts of environmental adaptability, serving for transportation and comprehensive benefits were followed. In the whole line of the railway, long-bridge scheme was adopted, and the most advanced technology of unballasted track was utilized in bridges which account for 87.7 % of the total line. The success of the design and construction of bridges in Beijing-Tianjin inter-city railway accumulated valuable experiences for large-scale construction of high-speed railway at the future. And roles of demonstration, landmark and prototype are played at the same time.
