Research on warning model of urban road collapsing based on GPR and fuzzy theory

In recent years, accidents of urban road collapsing occur frequently, which not only cause considerable economic losses, but also the casualties. For the various problems and potential security risks brought by urban road collapsing, this paper analyzes the factors of urban road collapsing and a new warning method based on dynamic tracking is put forward. And a warning model of hazard grade of urban road diseases is established based on GPR and the theory of fuzzy comprehensive evaluation. An application experiment has been conducted to the Binhe road and Huicui road of Zhongmu County to verify the new warning model. The result shows that: the warning model can effectively predict the hazard grade of urban road diseases in practical application, and provide effective technical support for the road maintenance and engineering treatment.
