Thinking and methods of intelligent supervision of urban geological environment based on big data

With the acceleration of urbanization, the rapid expansion of scope, the rapid expansion of population, the proliferation of high-rise buildings and the large-scale development of underground space, they are faced with great challenges, such as the dilution of water resources, the deterioration of geological environment and the frequent occurrence of geological disasters.In order to meet the challenge effectively, it is urgent to carry out fine and holographic three-dimensional geological modeling oriented to "intelligent city" on the basis of urban multi-factor geological environment survey and establishment of perfect information system, that is, to establish a new type of urban "glass land", to realize the temporal and spatial perspective of urban geological environment, and then to establish urban geological resources by using sensors, Internet of things and cloud technology.Finally, based on the assimilation, fusion and mining technology of geological science big data, intelligent early warning and control are carried out.
