Dynamic Response of Anisotropic Multilayered Road Structures Induced by Moving Loads Based on a Novel Spectral Element Method

This contribution is devoted to the analysis of three-dimensional elastodynamic problems in multilayered road systems caused by moving loads with static and dynamic components. For this purpose, a novel spectral element method (SEM) derived model layers half-space. To reduce order wave equations, state vector introduced, then transition matrix for upper lower boundaries layer. Based on use precise integration algorithm (PIA), very accurate numerical solutions can be obtained. The proposed was within 3D Cartesian coordinates, which facilitate complex or structures. stiffness does not depend tedious lengthy analytical solutions, conducive anisotropic materials. Numerical examples are presented compared those previous studies show accuracy effectiveness SEM. Additionally, further refined examining effects load speed properties displacement stress field stratified flexible pavement.
