The paper presents experimental studies on the geophysical study of the dam of the Big Almaty Lake. The object of the study was the dam of the Big Almaty Lake to prevent future emergencies, to identify the internal structure of the structure of the dam, the zone of leakage and moisture. The formulation of the problem requires the use of a fast and non-destructive method, in addition, the method must be economically feasible, accurate and provide significant savings in time and money compared to the available methods of visual observation of the object. Experimental studies were carried out using the geophysical instrument “Georadar “Loza B” along the foot and along the top of the dam using three-meter antennas with a step along the profile of 0.5 m. The experimental results were processed in the built-in software of the geophysical instrument. The conclusion is given on certain sections of the dam of the Big Almaty Lake and recommendations on further actions. The results of this work will allow us to further develop technology for interpreting radargrams and conduct a comparative analysis of experimental studies and the results of data from similar radarograms. The work was carried out within the framework of the project of the rector of Abai Kazakh National Pedagogical University “GPR studies of the physical parameters of the “Big Almaty” reservoir and computer modeling of the structure of the environment.”
