The Inversion Analysis and Material Parameter Optimization of a High Earth-Rockfill Dam during Construction Periods

Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it still difficult obtain calculation results that are consistent with due different construction statuses. To deal this situation and introduce a new improve accuracy, general method inversion based on back-propagation neural networks original step-by-step assuming parameters constitutive model vary periods introduced verified in work. Then, both methods applied high gravelly soil core rock-fill dam during periods. Moreover, relationship between inversed material stress values wall discussed. The further optimized more accurate displacement values. show has higher accuracy vertical compression compared conventional method, trend parameter K significant than other parameters, proposed variable methods. Conclusions can be drawn advantages paper might suitable for
