“…In future, we plan to apply and compare nonlinear mode decomposition methods (e.g. K-SVD (Aharon, Elad, and Bruckstein, 2006;Otake, Kodama, and Watanabe, 2019b), kernel PCA (Schölkopf, Smola, and Müller, 1998), robust PCA (Candès et al, 2011), the introduction of multiresolution representation, etc.) to investigate more appropriate contractions with feature extraction.…”

In recent years, improvements to the design of earth structures to ensure soil robustness against accidental disaster load conditions has gained considerable importance. In this paper, we propose a practical reliability analysis scheme that can enable the development of a robust design based on dimensionality reduction; this scheme employs input parameters, and it uses numerical analysis results as multidimensional information while preserving the spatiotemporal information to the maximum extent. Further, the proposed design scheme has practical design functions similar to those of conventional reliability analysis methods, such as the first-order second-moment method and first-order reliability method. Finally, the effectiveness of the proposed design scheme and its significant contribution to the practical design of earth structures are demonstrated via a time series seismic deformation analysis of simple embankments on liquefiable sand ground.
