Design of Railway Parallel Section of Tongcheng Avenue Expressway in Hangzhou
To welcome the 19th Hangzhou Asian Games and improve the expressway network in Hangzhou and Xiaoshan District,Xiaoshan District has started the construction of Tongcheng Avenue expressway.According to the overall layout of the whole line,one section is located within the scope of the railway business line 30 m from the center of the existing railway line.Through the study of the plane control elements,the route direction of the parallel section of the railway is determined,and the elevation points are analyzed to determine the vertical section elements.In order to reduce the impact of bridge construction on the railway,steel-concrete composite beams with high precast assembly rate are selected for the project.The design and implementation experience of Tongcheng Avenue construction can provide reference for similar projects.
