Research On The Development And Utilization Of Urban Underground Space In Qingdao

With the social and economic strength of the ascension of Qingdao and the demandof the urban development, urban underground space resource has become animportant strategic resources, the development and utilization of urban space hasbecome to realize the sustainable development of the city is one of the most importantways. The Qingdao urban underground space development and utilization planning ofunderground space to determine the key development areas for metro lines andstations, urban main road and the junction, central plaza (green), business center, citymountain, large residential area and large public facilities. The subway line as thedevelopment and utilization of underground space is very important in thedevelopment of the axis, the urban spatial structure adjustment and the improvementof the area function and plays a very important role. At present of the QingdaoMunicipal Government has been planning to build eight subway lines and a totallength of231.5km, is expected to be completed in2050, an investment of13billion,completed in2014.Qingdao commercial center at all levels of the present situation ofthe construction of the earth have basic tends to saturation, but to the development andutilization of urban underground space is actually serious insufficiency. Existingbusiness district of the commercial building is only a few developed undergroundspace as a supermarket and an underground car park, but the lack of a large,underground engineering construction alone, many of the commercial flow of peoplein the region has reached the degree of approach to saturation, commercial spacecapacity is urgently neededexpansion of underground space, such as the constructionof parking, commercial, cultural, dining, entertainment and other functional space isessential.In this paper, at first the urban underground space development and utilization ofthe domestic and foreign research present situation and development trend of thesystem summary and research, and argument will be part of the domestic and foreignresearch results and general rules applied to Qingdao underground space developmentand utilization feasibility; Then sum up the domestic underground space developmentand utilization of the city is relatively mature, the underground space developmentand utilization method system, and demonstrated the development and utilization ofurban underground space in our country the necessity. Learn from Beijing, Shanghaithese successful construction of underground space for the city’s experience,considering the actual situation in the city of Qingdao, Qingdao underground space ofthe building research and explore suitable Qingdao modernization of undergroundspace construction mode and function selection using the analytic hierarchyprocessdiscusses Qingdao demand for underground transportation, undergroundcommercial, municipal public buildings and civil air defense projects;In Qingdao cityunderground space development potential evaluation research, Qingdao construction future development and utilization of underground space resource in the form ofquantitative evaluation and importance of sorting, in order to improve the efficiencyof utilization of underground space to provide decision basis. Finally, this paper pointsout that the urban underground space development and utilization of the risk in theprocess, this paper discusses the hazards on the impact of urban sustainabledevelopment, and in the development process better avoid disaster, to ensure that thedevelopment and utilization of urban underground space smoothly.This article from many, many angles on the system analysis method and train ofthought, with the aid of engineering economics various qualitative and quantitativeanalysis method in Qingdao city, the development and utilization of undergroundspace makes a comprehensive and detailed analysis, research, the research methodand technical route can be applied to other parts of the underground engineeringresearch, and as a guidance and reference, make the research actuality, reduce theblindness of research, in constant application and practice, make the undergroundengineering research system is more and more perfect, more and more deeply. So thatthe underground space development and utilization and orderly, rational,comprehensive and efficient, and realize the sustainable development of the city.
