    The earth-fill dam state express investigation using mechanical vibrations produced by HPP by Galina Antonovskaya, Natalia Kapustyan

    Published 2022-12-01
    “… The usage of mechanical vibrations produced by the hydropower plant (HPP) turbine may be used for seismic sounding of large-scale constructions as the earth-fill dam and its abutment contacts. Such vibrations are monochromatic oscillations on main frequencies and their harmonics produced by turbine. …”
