Dynamic Responses of the Pile-Saturated-Soil System to a Moving Load

According to the basic solution of viscoelastic and saturated soil subjected to moving load on the surface and circular uniform harmonic load on the inside, the integral equation of soil-pile interaction under moving load in frequency domain is established by using Muki virtual pile method, and then the time-space dynamic response characteristics of a single pile in viscoelastic saturated soil to moving load vibration source are analyzed by using inverse Fourier transform. The factors that affect the dynamic response of single pile, such as load speed, length of single pile, saturated soil parameters, vibration source properties, etc., are analyzed and compared with the known results in related literature.
