Abstract:In recent years, the development of urban construction and the development and utilization of underground space have not only brought convenience to the people's lives, but also led to the occurrence of urban road diseases to a certain extent, and the frequent occurrence of road collapse accidents has prompted the need for a comprehensive physical examination of urban roads. Based on the principle of GprMax of the three-dimensional finite difference time-domain method, the propagation characteristics of geological radar in inflatable pipelines, square culverts, cavities, etc. are numerically simulated, and the forward characteristic model of radar images is preliminarily established.
