Land Subsidence Prevention And Urban Construction Of Sustainable Development Research Of Tianjin

As an important coastal open city and port city in north China, Tianjin belongs toa typical water-lack city which is seriously short of surface water for a long time, it isthe main cause of the geological disaster of urban land subsidence to be Forced toover-exploite the groundwater. The urban geological environment deterioration andthe destruction of different degrees of the infrastructure construction affect the overallurban development planning and economic and social sustainable development inturn.With the deepening of the "twelfth five-year" plan in Tianjin, it becomes themajor topic for the prevention and control of land subsidence to further play afundamental role of the geological work in accelerating the development and openingand in the economic and social all-round development of Binhai New Area, ensure thesecurity of the urban geological environment and the harmonious development ofsociety, how to adopt a more scientific and rational technology and management,coordinate various environmental and social factors, get the new breakthroughs in theprevention and control of the land subsidence.Based on the experiences and the problems of the previous work, this paperfocuses on the economic efficiency analysis and feasibility countermeasures of theprevention and control of land subsidence; puts forward reasonable suggestions in thescientific research, scientific monitoring, scientific computing, scientific managementand the scientific prevention combined with the current technology research, themanagement decision and the prominent contradiction of the social cognition tocoordinate the relationship between service of urban construction and the protectionof geological environment; the suggestions are to fully aware of the importance of theprevention and control of land subsidence, increase publicity and education;strengthen organization and leadership, straighten out the management system;makeplans of prevention and control of land subsidence in Tianjin, strengthen theconstruction of legislation and law enforcement supervision; deepen the research onthe technology of the prevention and control of land subsidence; perfect the system ofthe land subsidence monitoring, promote the construction of demonstration project;establish deep monitoring marker, and the major engineering special monitoring; Setup the demonstration project of the monitoring and comprehensive treatment of landsubsidence.
