Abstract

Medium-pressure hydroelectric power plants were studied using the standing wave method. Highly accurate data on transverse, longitudinal, and vertical natural oscillations of the Nizhnekamsk and Novosibirsk hydroelectric power plants were obtained. The results allow one to use the obtained maps of standing wave amplitudes in structures to determine their block structure and to verify the calculated models of hydroelectric power plant dams, to form conclusions on the seismic resistance of objects. The results are important for filling in dam passports and for design work on creating a system of engineering and seismometric monitoring of dams.
