Research Of Hangzhou Underground Space Development And Utilization

Underground space as a kind of precious natural resources, many countries all over the world to it in the orderly, rational, economic and efficient development and utilization, it will be widely applied in traffic storage, air defense, environmental protection, energy, residential, commercial, etc.With nearly thirty years of rapid economic development, hangzhou urbanization process more and more quickly. The urban population has increased dramatically, urban traffic congestion, land nervous. The ground space height intensive and land price jump to start a large-scale urban underground space development and utilization. In the21st century, hangzhou has started a large-scale urban underground space development and construction of exploration, the construction of a batch of large underground space project, such as subway, underground street tunnel and underground commercial center, underground parking library, underground municipal common pipe trench, etc. But because of the lack of comprehensive utilization of underground space planning, systematic decision-making and the marketability operation, underground space the waste of resources is serious.Hangzhou municipal underground space development is rapidly from dispersible towards unity concentration and network, three-dimensional, intensive and deep, comprehensive direction transformation, establish and perfect the decision-making, execution and supervision according to law and set up the separation of administrative decision-making management mode, the innovation of urban underground space development and construction management and operation guarantee mechanism of urban underground space development is an inevitable requirement. The underground space development in hangzhou construction management mechanism and mode, management mechanism and operating mode and underground space development and utilization of the operation security system research, is hangzhou cope with the construction of underground space resource insufficiency, the underground space to promote the healthy and orderly development request inevitably.To carry out large-scale urban underground space development premise is to have a perfect underground space planning system and laws and regulations. Diversified investment and financing channel is to make urban underground space development and utilization and urban keep pace with the development of the key factors. Urban underground space efficient underground space development and utilization project management is underground space project can be carried out smoothly and perfect guarantee of consign is used. To realize the urban underground space development and utilization of effective and obtain high yield, cannot leave the underground space of the maintenance and operation security.This research significance lies in the urban underground space development and utilization focus from engineering technology turn to project planning and management level. The underground space research focuses on legal system construction, planning system, the establishment of project management, project investment and financing and project operation maintenance. To promote the study of hangzhou city underground space development and utilization process is of great significance.
