Application of Ground-Penetrating Radar to Detect the Continuity of Strata around Pipelines

There are more attendant problems with China's urban pipeline project developing rapidly, and the density of the formation surrounding the pipeline becomes an important issue. Therefore, the detection of the position and scope of less density and the cavity area around the pipeline have become top priorities of piping. This paper combines the process of a geological radar to detect the stratum around a pipeline in Xi'an to introduce the application of ground penetrating radar to detect less density and the cavity area around the pipeline. The conclusion shows that the amplitude of the radar reflected wave is in an approximate inverse relationship with the density of the stratum.
