Calibration of Finite Element Models for Concrete Gravity Dam-Foundation Systems Using Historical Field Monitoring Data: Comparative Analysis with Statistical Approaches

We proposed methods for developing predictive models of concrete gravity dam crest displacement. A deterministic finite element analysis (FEA) model is presented along with a method for identifying its mechanical properties. Performance of FEA model is compared to booster regression trees statistical model with hyperparameter tuning. Resulting models demonstrate excellent accuracy.
