Study On Related Problems Of Introducing Passenger Dedicated Line Into Railway Terminal

With the sustainable development of national economy,the pace acceleration of urbanization construction, and the increase of people's incomes, people put forward higher requirements for the comfort, rapidity, and safety of travel. In order to establish in an invincible position in the increasingly fierce market competition, on the basis of reform of " raising speed ", the railway develop the passenger dedicated line vigorously to realize separate running of passenger and freight trains, therefore, many passenger dedicated lines will be introduced into terminals in succession. Study how to introduce passenger dedicated line into terminal, how to compare and select the superior plan from numerous introduction plans, how to design the station and lines joint reasonably, and so on, become especially important.Through combining with theoretical analysis and actual planning, according to introducing Chengdu-Mianyang-Leshan intercity passenger dedicated line into Chengdu terminal, this paper carries out the research of the following contents. First, the paper comprehensively analyze the related influencing factors of introducing passenger dedicated line into terminal, to provide the reliable basis for determining the location of passenger dedicated line station and the introduction plan. Second, this article carries on a systematic research to introducing passenger dedicated line into terminal. On the basis of function orientation of passenger dedicated line station, according to the methods and principles of location selection, this paper obtains several kind of preliminary introduction plans. Then it carries on the technical and economic analysis to each plan, builds the AHP-fuzzy comprehensive evaluation model of plan comparison and selection, and selects the optimum plan through combining qualitative analysis and quantitative analysis. And according to the final introduction plan, the paper carries on research to the passenger dedicated line station layout, and designs the station throat, the untwining plan, and the reasonable lines joint. Third, from the system point of view considering, the article studies on the transportation organization mode, passenger station division, station regional planning, and passenger flow organization after introduced passenger dedicated line into terminal, in order to reflect the coordinated development with transportation organization. Finally, on the basis of previous theoretical study, taking introducing Chengdu-Mianyang-Leshan intercity passenger dedicated line into Chengdu terminal as an example, the paper describes the design idea of introducing passenger dedicated line into terminal in detail.This paper uses the principle of comprehensive evaluation, builds the AHP-fuzzy comprehensive evaluation model which combines analytic hierarchy process and fuzzy comprehensive evaluation to evaluate the passenger dedicated line introduction plan. In the course of whole study, the thesis pays attention to the close combination of theoretical research and actual planning, studies the concrete plan of introducing Chengdu-Mianyang-Leshan intercity passenger dedicated line into Chengdu terminal, and forms a set of complete theoretical system and design idea on the research of introducing passenger dedicated line into terminal. To a certain extent it has an innovation in methodology, and it also has certain theoretical and realistic significance to the study on the related works of passenger dedicated line.
