A New Method on Probing and Interpreting Underground Pipeline's Diameter by GPR

The GPR (ground penetrating radar) method is always used to locate embedded pipes. However, it is hard to determine their diameters, especially when the underground pipe is full of a lossy medium (as water, oil, or gas) in the operation period. This paper first puts forward a new method for probing and interpreting the diameter of underground pipeline filled with the lossy medium. By means of the GPR, the shape of a certain circle can be determined by the coordinates of three points on this circle. Moreover, the operation procedure of this method is listed in detail. Lastly, this method is applied to detect the diameters of the underground pipelines in the model experiment of the actual project. The measurement value is approximately consistent with the real value. This demonstrates that the proposed method achieves good results.
