The Research On The Longitudinal Design Parameters Of The Main Tracks Of The High-speed Railway Station

In the railway engineering design, design of railway station and yard is one of the important links, it is not only related to how to design a layout reasonable, safe and efficient station, more importantly, the station and the hub is the formation and realization of integrated transport capacity of the key link, it he most basic one of the infrastructure which determines whether the requirements of railway transportation can service or not.In the design of railway station, railway station vertical section design technology has become the current railway engineering field to study, because it has very important significance of high-speed railway station to realize reasonable economy, safety and reliability, convenient and efficient overall demand.This paper take high speed railway in the background, I take CRH-3as the main research models, discuss the station lines vertical section design parameters. In the maximum slope angle, discussed to meet the train stops after the smooth start and stop without sliding under two conditions of considering of the wind effects and not in case of critical slope angle. In the discusse of the minimum slope length, the two sections are both conserned. In the longitudinal vertical curve radius of curve study, I discuss it according to passenger comfort and safety of train running. This paper is to discuss through theoretical calculation under certain environment and some other specific conditions parameter theory value, for reference of designers.
