Résumé

Determining the possibilities of using the ground penetrating radar method, which is a method of shallow geophysics, in seismically active areas will increase the information content and reliability of the results, especially in engineering and geological surveys to ensure seismic-resistant construction in geodynamically active areas, which include Kamchatka. To optimize the ground penetrating radar method, it is necessary to compare and analyze the results of observations in various geological conditions. Since the ground penetrating radar method has been intensively developing in recent years, theoretical research in the field of data processing must be illustrated by numerous examples of the practical use of ground penetrating radars at various research sites. The purpose of the research is to create a scientific and methodological basis for the georadar method in relation to Kamchatka, including methods for processing and interpreting data, taking into account practical experience of application at various sites. The object of the research is the geological features and soil conditions of the territory of the Petropavlovsk-Kamchatsky city, requiring clarification and detailed study. The article describes the experience and features of working with the «Triton-M» georadar device in the Petropavlovsk-Kamchatsky city. Some results of ground penetrating radar profiling are characterized. Recommended values of measurement parameters during work are given. From a practical point of view, the most important parameters of the ground penetrating radar are the probing depth and the depth resolution. The «Triton-M» ground penetrating radar device is applicable for solving geological problems in the territory of the Petropavlovsk-Kamchatsky city, while optimally selected values of measurement parameters minimize the recording of interference and provide more accurate useful information about the probed environment. For accurate interpretation of radargrams, it is necessary to use information about the geological structure of the studied territory.
