RESEARCH OF DAM AT BOGUCHANY HPP BY THE STANDING WAVES METHOD
The dam at Boguchany HPP was researched by the standing waves method. Four natural frequencies of a stone dam have been identified and the fact of the absence of resonances in the stone-bulk part of the dam have been determined. The block structure of the concrete dam influence on the dam's natural vibrations. So at the frequency of 3,222 Hz, the first mode of the station part of the dam was studied, and at the frequency 3,515 the third mode of the station and deaf parts of the dam was investigated. Two more standing waves are the sixth and eighth modes for oscillations in a concrete dam as a whole. The obtained data are important for the experimental substantiation of dam models and for the system of engineering-seismological monitoring.
