Evaluation Of Underground Space Resources In Tianjin Binhai New Area

With the accelerated process of urbanization in Binhai New Area,the scale of the city has been expanding,the population has expanded rapidly.There have been a series of problems,such as shortage of construction land,traffic congestion and backward infrastructure.At present,many developed countries have made the development and utilization of urban underground space as an important measure to cure the "urban syndrome",and have also been heavy space resources and technical means to expand,China large city clear for the modernization of city land intensive and efficient use of space,improve traffic conditions and environmental protection.“Tianjin Binhai New Area Urban Master Plan(2005-2020)" clearly put forward "according to the city's overall spatial distribution,rational planning and use of underground space" specific requirements.Considering from the angle of feasibility,influence the development and utilization of underground space by geological conditions,hydrological conditions,ground space types,existing underground facilities,construction difficulty,economic strength,economic benefits,social benefits and many other factors.In addition,the urban underground space resource has the characteristics of invisibility,irreversible and other notable features,which makes the difficulty and complexity of the underground space planning more than the traditional urban planning.In view of this,it is necessary to evaluate the quantity and quality of the underground space resources in the early stage of development,so as to provide the basic data of macro potential and quality characteristics for the development and utilization of underground space,and the layout and development schedule of underground space.In this paper,the comprehensive quantity evaluation of underground space resource is carried out based on the data of spatial situation,hydrogeology,engineering geology and adverse geological actions.It provides the basic data and scientific support for the comprehensive utilization and planning of underground space in Tianjin Binhai New Area.
