Subject: as a result of long break in construction of Boguchany HPP and the impact of external climatic and anthropogenic factors, aging and local destruction of concrete gravity dam took place, which necessitated repairs. The article deals with the geophysical methods used to assess the effectiveness of repair work on concrete dam of Boguchany HPP. Goals: the goal of the research was the quality control of works on the “healing” of concrete in the sections of abutment of a concrete dam to a rock-fill dam using a complex of geophysical methods, and determination of elastic and strength properties of concrete. Materials and methods: a set of geophysical non-destructive methods is proposed, including ultrasonic examination and seismotomography. To analyze the obtained materials, histograms and cumulative curves for distribution of values of the obtained velocities of elastic waves of the entire investigated region have been constructed. Results: the study showed that the repair works carried out had a positive effect on the elastic and strength properties of concrete. This is confirmed by a decrease in the area of structure’s regions in which the reduced parameters were observed. Conclusions: the proposed set of research methods has proved its effectiveness. It allowed us to obtain sufficient amount of experimental data on the state and quality of concrete at Boguchany HPP.
