MATHEMATICAL MODELING IN SYSTEMS FOR OPERATIONAL EVALUATION OF THE STRESS-STRAIN STATE OF THE ARCH-GRAVITY DAM AT THE SAYANO-SHUSHENSKAYA HYDROELECTRIC POWER PLANT

摘要

Current studies of the stress-strain state of the dam at the Sayano-Shushenskaya Hydroelectric Power Plant at VNIIG based on mathematical modeling including full scale and experimental data are described. Applications and programs intended for automatic operational evaluation of the stress-strain state of the dam for optimizing control of the upper race level in the course of the annual filling-drawdown cycle and during seismic events are examined. Improvements in systems for monitoring the stress-strain state of concrete dams are proposed.
