With the rapid expansion of urbanization in China, the road collapse accidents are frequent and recurring, which seriously threaten the social security and cause the adverse social impacts. Under the background of building a resilient city, the prevention of road collapse accidents has become an important task in the urban construction management. Therefore, it is to determine the method effectively to detect the road collapses. It is important and practical significance to analyze the causes of typical road collapses. The applicability of the detection method is determined by comparing the geophysical prospecting data before and after causing the cavity in a typical area. Through the pipeline endoscopic detection and road settlement monitoring, the development process of the collapse is analyzed, and the relevant suggestions are put forward to provide a basic basis for the prevention and control of road collapse.
