RETROSPECTIVE ANALYSIS OF THE RESULTS OF GEOPHYSICAL MONITORING OF THE FOUNDATION OF THE SAYANO-SHUSHENSKAYA HPP IN 2011 - 2019

摘要

The variation of the velocity of P-waves in the base and abutments of the dam and in the foundation of the powerhouse is analyzed. The zones of man-induced impact are identified, the background and abnormal variations in the velocity of P-waves in the abutments of the dam are determined, and the design and current values of the deformation modulus are compared.
