Transient Dynamic Response Analysis of Two-Dimensional Saturated Soil with Singular Boundary Method

In this paper, the singular boundary method (SBM) in conjunction with exponential window (EWM) is firstly extended to simulate transient dynamic response of two-dimensional saturated soil. The frequency-domain (Fourier space) governing equations Biot theory solved by SBM a linear combination fundamental solutions. order avoid perplexing fictitious solution (MFS), places source point on physical and eliminates singularity via origin intensity factors (OIFs). EWM carried out for inverse Fourier transform, which transforms solutions into time-domain accuracy feasibility SBM-EWM are verified three numerical examples. comparison between MFS indicates that takes quarter time taken MFS.
