Quantification of Dynamic Properties of Pile Using Ensemble Empirical Mode Decomposition

Quantification of Dynamic Properties of Pile Using Ensemble Empirical Mode Decomposition

This paper investigated dynamical interactions between pile and frozen ground by using the ensemble empirical mode decomposition (EEMD) method. Unlike the conventional empirical mode decomposition (EMD) method, EEMD is found to be able to separate the mode patterns of pile response signals of differ...
