Abstract
The Gaochun section of Ning-Gao Intercity Rail Transit is one of the planned lines, which connects Dongshan urban area, Shiqiu new town and Chunxi new town of Najing, and which mainly undertake the long-distance trip between main urban area and Gaochun area. Dedicated preliminary study of system mode determines that the target speed of this line is 120 km/h and 4-B type-car train set is selected. However, there are no related design criterions of such railway lines in China and related design standards of subways and national railways need to be referenced. However, the horizontal and vertical design of this line is very different from that of subways and national railways, thus, codes for metro design or codes for design of railway line can hardly be referenced completely. Therefore, the critical technical parameters of this line should be specially studied and suitable technical standard is selected, and critical technical parameters are calculated according to the functional orientation and characteristics of the line.关键词
