An Evaluation Method of Crack Variation on Structural Performance of Concrete Dams with Fusion Entropy Based on Observation and Simulation

This study proposes a method for evaluating crack variations on structural performance of concrete dams using observational and computational output. The is represented by the system entropy in dams, stress-strain field established incorporating observations simulations calculations. Considering characterization ability sample points, weighted sequence constructed with selected index system. Thereafter, fusion successively separated analyzed rescaled range (R/S) analysis, Hurst exponent difference corresponding warning indicators are calculated to quantify destructiveness variation. application presented elaborated arch dam, behavior J01-crack exhibits no significant its condition. analysis results verified feasibility proposed evaluation dams.
