摘　　要：为迎接第19届杭州亚运会的召开、完善杭州市和萧山区快速路网,萧山区启动了通城大道快速路的建设工作。根据全线总体布置,其中一段位于既有铁路线线路中心30 m铁路营业线范围内,通过对平面控制要素进行研究,确定铁路并行段路线走向,同时对高程点进行分析,确定纵断面要素。为减少桥梁施工对铁路的影响,工程选用预制装配率较高的钢-混组合梁。通城大道建设的设计与实施经验可为类似工程提供参考。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.
