Abstract

Purpose. Improvement of the seismicity monitoring system and implementation of a new digital system of engineering and seismometric observations with a modern base for processing seismometric information at the hydraulic structures of Uzbekistan.

Methods. Introduction of digital recording of waves for assessing oscillations of the dam and the coastal part of the Charvak reservoir.

Findings. The frequencies and oscillation rates of the dam body and the coastal slopes are determined in automatic mode without operator intervention. The ratios of the amplitudes of the oscillation velocity in measuring points to the amplitudes of the oscillation velocity of the dam base or the coastal slopes of the Charvak reservoir are calculated. When registering different earthquakes at different points, these relations vary significantly depending on the azimuth of the arrival of waves. Reservoir soils are categorized by seismic properties.

Application field of research. The obtained experimental data can be used to assess the conditions of oscillations of high dams of the Charvak reservoir during strong earthquakes.
