Research On Location Selection And Station Layouts Of Psl Passenger Station In A Railway Hub

With the construction of the passenger special line in our country, the passenger station, as the key point of the "node-line coordination" part, is on rapid construction and development. There will be 548 railway passenger stations been built or reconstructed and expanded during the "Eleventh Five-Year" period according to the plan.This paper makes a systematic study of the adaptability of passenger station terminal layout and the pros and cons choices of the communication station fields layout that converge urban railway from the perspective of the connection with the terminal set.The study includes:(1) This paper summarized the concept and types of the railway hubs and, analyzed the setting characteristics of the railway terminal in china.(2) The author analyzes the factors that influence PSL passenger station layout, sums up the railway terminal passenger station's layout, and selects the layout programs adaptability for the passenger station on the railway terminal properly.(3) The author analyzes sorts of 2D and 3D layout of the passenger stations on PSL on condition of rail being or non-rail being.(4) For the characteristics of subjectivity for the indicators of PSL layout selection by using the entropy theory to improve the weight coefficient of fuzzy comprehensive evaluation in order to make a optimal selection of pessenger station layouts.(5) Taking the new Chengdu station as an example to study the layout and work devision of Chengdu railway hub.Then, evaluating new Chengdu station layout projects by using the entropy theory-based fuzzy comprehensive evaluation. Finding that 2 yards project is superior than 3.This thesis uses and develops the passenger station/terminal layout theory, comprehensive traffic integration theory and the entropy theory, etc., around the terminal passenger station set on passenger special railway line. By using transportation systems analysis, fuzzy mathematics and comprehensive evaluation, the author makes a systematic study of the scheme of passenger station layout on passenger special line.
