Abstract:
Based on the equation of motion under the elastomeric excitation and the superposition theory of incident and reflected wave, combined with the coordinate transformation and Fourier transformation, a spectral element method of analyzing the dynamic response of elastic half-space soil under moving loads was established. The dynamic responses of various mechanical property indexes in the road of the practical examples were analyzed and the vertical displacements of the point change relationships due to different load speeds, load frequencies as well as damping ratios of soil were gained.The calculation results were compared with the other methods. The results show that spectral element method has feasibility and rationality.
