Abstract
Urban utility tunnel has been regarded as an important symbol of urban modernization, so it is important to understand the quantized relationship between city development and urban utility tunnel for city management and policy making. In this study, the internal relationship between the development amount of urban utility tunnel and urban population density was discussed, as well as urban GDP per capita, urban construction land area per capita and urban land price index, based on the IBM SPSS platform, through adopting the development amount of urban utility tunnel and the urban development data of the past 46 years of Japan. It was shown that the correlation relationship of the development amount of urban utility tunnel with the density of urban population was comparatively strong negative, and relatively strong positive, comparatively strong positive, relatively strong negative for GDP per capita, urban construction land area per capita and urban land price index respectively, which explained the driving effect that urban development imposed on urban utility tunnel construction in essence. Furthermore, a quantitative model was proposed for the relationship between the development amount of urban utility tunnel and urban development indexes, and the model could be a reference for decision making of urban utility tunnel development in China and other countries.
Highlights
Throughout the centuries, urban utility tunnel has been regarded as an important symbol of urban modernization, and be an inevitable product of city development, which has been proved by the development history and experience of developed countries [1,2,3,4,5,6,7,8,9,10]
Urban population density reflects urban population, the level of urbanization, the environmental pressure and the situation of urban society; urban GDP per capita corresponds to the level of urban economic development and the situation of urban society; urban construction land area per capita is a mirror of the scale of urban construction, the urban landscape and the urban ecological environment; urban land price implies the levels of urban economy, population and social development
The data of the amount of urban utility tunnel development of each year in Japan were obtained from the references [16,17,18,19], in which these official statistical data were done by the Japan Tunnelling Association
Summary
Throughout the centuries, urban utility tunnel has been regarded as an important symbol of urban modernization, and be an inevitable product of city development, which has been proved by the development history and experience of developed countries [1,2,3,4,5,6,7,8,9,10]. Systematic research has been carried out with a variety of engineering practices [11,12,13,14] It leaded to the establishment of reasonable design, planning, financing and standard systems which has been worked out successfully in the mass construction of their own countries [11,12,13,14,15]. Urban utility tunnel construction in Japan had little further progress until the 1950-1960s. The Japanese government started to develop utility tunnels rapidly at the same time as its road construction program (see Figure 2) [16,17,18]. In order to make clear the connotative meaning of developing urban utility tunnel, it is advisable to give an insight into Japan’s experience. The flowchart of this research methodology was shown Figure 1
