| Abstract: | Reverse curve is unusually adopted in difficult section of railway line during its design in urban rail transit project.Design of gauge is an important problem related to driving safety in reverse curve section.By comparing two existing migration calculation methods of tunnel center line,their advantages and disadvantages of design in reverse curve section as well as the notices are proposed,and some rational suggestions are given on length design of intermediate straight line from the perspective of metro ... |
