Study on the current situation and application direction for the hidden disease identification of urban roads based on geological penetrating rada

The problem of hidden diseases in the vast urban road network has gradually become a prominent problem that restricts urban development. Geological penetrating radar (GPR) is widely used in the identification process of concealed diseases because of its light weight, maneuverability, easy operation, clear and easy-to-understand interpretation data. Based on the typical case of urban road defect GPR in China, this paper introduces and evaluates the research status of equipment development, recognition effects, and recheck plans, thereby providing a reference for the more efficient surveying of urban roads. Finally, preliminary ideas for constructing a detection-maintenance system based on GPR under the GIS urban information management monitoring platform are discussed in order to better serve the road management department and formulate a better and more reasonable road repair and maintenance program.
