Study On Station Yard Design And Parameter Optimization For High-Speed Railway

The design of station yard is an important step in railway engineering. It's not only related to the station design, what's more, station and terminal are the key links to generating integrated transportation capacity and is one of the most basic infrastructures to meet the need of service quality in railway transportation. The high-speed station yard undertakes the receiving and sending of universal speed train, high-speed train and intercity transit train. It has numerous tracks and the works are complex. The yard design should meet the adjustment of transportation and operations in peak hours, meet the need of technical operation, assure the tracing and improve the service quality. The high-speed station yard should also assure the mutual coordination and complement between every yard, and making the high-speed railway play it's maximum transportation capacity in normal conditions and non-normal conditions. The design technique of high-speed station yard is a prominent subject in railway engineering. It is very significant to realize the general requirement of economic and reasonable, safe and reliable, efficient and convenient high-speed station.Base on the analysis of high-speed station yard setting, the design of high-speed station yard and parameter optimization are researched using all-weather operation simulation theory, Combined with the practice of yard design, the capacity adaptability of the throat area and main facility is systematically analyzed and studied. Base on fully considering the wheel-rail contact relationship in turnout area, model used in analyzing parameters of connection curves in high-speed station yard are established. Effecting rules on vehicle-line dynamic responses by lateral passing speed, attaching length, length of insert lines and length of transition curves are analyzed. Proper values of connection curve length are proposed from the view of comfort, safety and wears. Theoretic basis and reference suggestions are provided for high-speed station yard design and parameter matching.The respective number of graphs, tables and refs is 115,21 and 102.
