The isolation of the vibration due to a harmonic vertical load using pile rows embedded in a saturated poroelastic
half-space is investigated in this study. Using the fundamental solution for a circular patch load and Muki’s method,
the second kind of Fredholm integral equations describing the dynamical interaction between the pile rows and the saturated
poroelastic half-space are obtained. Numerical solution of the integral equations yields the dynamic response of the
pile-half-space system. The vibration isolation effect of the pile rows is investigated via the proposed semi-analytical
model. Numerical results indicate that stiffer piles have better isolation vibration effect than flexible piles. Moreover, the
pile length and the spacing between neighboring piles in one pile row have significant influence on the isolation vibration
effect of pile rows, while the influence of the spacing between neighboring pile rows is relatively smaller.
