Abstract

An analysis of the design features, indicators of strength, stability and condition of the hydraulic structures of the Eshkakon hydroelectric complex according to the project data, verification calculations and fi eld observations indicates that the most vulnerable structure to the impact of natural and man-made hazards that can cause a hydrodynamic accident is a rock-and-earth dam. As a factor of natural impact on the hydraulic structures of the Eshkakon hydroelectric complex, an accident at the dam from a seismic impact with a force exceeding the calculated value can be considered. Regular field observations and research, maintenance and repair activities carried out regularly ensure the constant maintenance of hydraulic structures in working condition. For the localization and liquidation of possible dangerous large-scale damage and emergencies at the facilities, the material and technical means of the owner of the facility are suffi cient. Improvement of the technology of liquidation of accidents and strengthening of technical means of emergency protection is achieved by carrying out a set of special measures, including organizational, preventive, repair and structural and technical solutions for preventing accidents.
