Geological and underground pipeline detection was carried out in several urban metro exit areas in the loess area by using ground penetrating radar (GPR). The distribution of soil layer in the loess area was emphatically studied. The GPR images of PVC pipelines and metal pipelines in the loess area under the conditions of holes, seepage and soil collapse were analyzed, and the respective GPR scans of underground pipelines in the loess area were summarized. By describing the characteristics of the images, the authors summarized the general analysis methods and rules of applying GPR to detecting urban geological stratification and pipeline radar images in the loess area, and used the image laws of "black-white-black" and "white-black-white" to analyze the GPR images, which provides a good guidance for subsequent engineering construction.
