| Abstract: | The scattering and diffraction of plane P waves by shallow circular-arc foundations imbedded in saturated soil is studied in this paper with the saturated soil simulated by Blot dynamic theory for saturated porous media. The Fourier-Bessel series expansion technique is used to solve this problem. Numerical results are given to illustrate the influence of different elastic behaviors of foundations on saturated soil-foundation interaction under the incidence of plane P waves and a detailed analysis of amplitudes and spatial variations of site ground motions is presented. |
