Abstract:

In the paper, the influence of the changes of plans on the plan layout of Metro lines, the layout of Metro stations, the layout of future Metro lines and the layout of longitudinal profiles of Metro lines is analyzed, with the design of Line 2 of Nanchang Metro as an example. Conclusion is drawn that in the early stage of the design of the Metro lines (such as in the Metro line location design stage, Metro station location design stage and longitudinal profile design stage), timely response should be made to the changes of the plan and that the design should be prospective, flexible and adaptable enough so that the Metro lines designed can match the city development well. 
