Research On The Coupling Of Space Structure In High-speed Railway Transportation Hub And Urban Transportation Organization

The increasing development with the characters of convenience, efficiency and energy-saving, the high-speed railway have been constructed8951km along with large numbers of railways were come into operations like Jinghu, Jingguang and Hada till the end of year2012. Meanwhile, cities along the high-speed railway began to face the construction needs of high-speed railway transportation hub, whose space structure would be effect by the located cities’transportation organization. On the contrary, the development and the layout of the transportation hub would influent the connections with the other kinds of transportation.In the first chapter of this paper, the author discussed about the recent developments of the high speed railway transport hub and the research significance that the developments could bring on the space structure in the railway transport hub and the urban transportation organization. Starting from researching the space structure and the transportation organization both domestic and abroad, the author brought up with some related research methods and the frame structure of the whole paper.In the second chapter, the author did researches on both the transportation organization and the space structure in high speed railway transport hub, and obtained several main kinds of forms in the transportation organization and the space structure. Based on that, the author discussed about the explosie developing process of high speed railway in the rapid urbanization period and summarized all kinds of transport hubs in our country. Through analyzing the main factors that could influence the developments of high speed railway transport hub, the author also have gained the classification methods which comforted to the present national conditions, on both the transportation organization and the space structure of high speed railway transport hub.When it came to the third chapter, the author presented the definitions, the contents and the objectives of coupling, and it also introduced some coupling modes resulting from the coupling mechanism between the transportation organization and the space structure in high speed railway transport hub. After analyzing the different kinds of processes of coupling modes, the author summarized several coupling developing modes in the paper. In the end of this chapter, the author evaluated the competitiveness of different kinds of coupling modes separately receiving that the coupling mode of the "complanation development——public transit" and the "three-dimensional development——public transit" is the optimum coupling mode between the space structure and the transportation organization in high speed railway transport hub.In the fourth chapter, proceeding from analyzing all kinds of factors which could influence the space structures of different transport hubs in China, the author came out with the construction principles on the coupling mode of high speed railway transport hub. And the author also did the dual optimization on the coupling mode in the summarizations of successful coupling developing modes.The fifth chapter of this paper proposed the dual optimization method on the space structure of transport hub, and it obtained the dual optimization graph in transport hub via the coupling developing modes between the "complanation development——public transit" and the "three-dimensional development——public transit" so that it could reach a conclusion on what direction the development of high speed railway transport hub could go and how the coupling developing modes could perfect itself.
