Abstract
Summary
The article presents the results of ground penetrating radar (GPR) researches of the gas subway pipeline, which was passed under the river by horizontal drilling. GPR method allowed to distinguish the layers boundaries in more detail than drilling data, and also found an anomalous zone with a high-frequency "ringing", corresponding to a metal object that damaged the upper part of the gas pipeline.
