A Study On Development And Use Of Underground Space

21st century will be the century of the underground space, with the constant improvement of the urbanized level, the problem is more and more serious that crowdedness of urban space, traffic jam, environment worsen, resources are deficient,etc., want the space from high altitude and underground, has already become and strengthened urban functions, essential means to improve urban environment, and the development and utilizing of the underground space of city causes the attention of investors and urban planners more and more among them. Melting stereoscopically and developing and redeveloping and already becoming important means to solve deterioration of the environment of space crowdedness of the centre of the city, ground of the centre district in the city; Effective measure that the construction of the subway relieves the traffic pressure as the big city; It is in charge of the corridor and become and strengthen urban functions, important routes to improve urban anti-disaster ability synthetically to build the underground pipeline; The construction of the large-scale underground communal facilities carried on for building the saving city has already become every great urban development trend of the world. In addition while urban construction, develop and utilize the intersection of city and underground space can also solve original cityscape and the intersection of city and contradiction of modernization effectively. This text uses the underground space relevant to absorbing both at home and abroad for reference and develops advanced theory and successful experience utilized actively, develop the underground space of Nanjing by carrying on research. Relevant concept and theory that this text introduces the underground space of city and develops at first, having introduced concept and potential value of underground space resources, macroscopical background and strategy meaning ofdevelopment of resources of underground space of city of our country, development value and comprehensive benefit of underground space resources, the theoretical foundation that the underground space of city utilizes, the underground space of city is developed and strategic objective and planning principles utilized, have analyzed two stages when the underground space of city is developed. Then has reviewed the underground space of Nanjing city and developed history utilized, has introduced the underground space of Nanjing city and developed and utilized the potential enormous demand especially, and analyzed the underground space of Nanjing city and developed the current situation utilized. Moreover, having introduced practice that the underground space of foreign city utilizes, four main reasons of expounding the fact the underground space of foreign city utilizes; Introduced practice that the underground space of city of our country utilizes at the same time, analyzed the underground space of city of our country and developed the development trend utilized, and summarized the underground space of domestic and foreign city and utilized to develop inspiration and reference utilized to the underground space of Nanjing. Finally, the subject problem of existence while summarizing the underground space of Nanjing city to utilize from five respects; Have put forward the underground space of Nanjing city to develop the countermeasure utilized from seven respects according to the detailed conditions in Nanjing. Hope to explore the underground space reasonable exploitation way of urban land resource of Nanjing, overcome and relieve all sorts of problems and pressures faced in city’s development, promote the vigor and competitiveness of the city, promote the sustainable development in Nanjing.
