摘要：

A classification is presented of the thermal states of the Sayano-Shushenskaya HPP and methods of identifying them by analysis of the thermal components of radial displacements obtained by the results of finite-element modeling. Based on the safety conditions of the repaired dam zones and the foundation, limit levels are presented for the entire path of filling-and-drawdown of the reservoir, depending on the thermal state of the dam. There is an evaluation of the dynamics of changes in the stress-strain state of the concrete of the dam face, based on finite-element calculation results and measurement data. Reasons are established for crack formation in the repaired zone and the effectiveness of measures taken to regulate the modes of filling-anddrawdown of the reservoir. © 2023, Springer Science+Business Media, LLC, part of Springer Nature.
