摘要：
The analytical layer-element method is used to solve the transverse isotropic multi-layered soils, and the finite element method is used for the piles. Considering the displacement coordination and the equilibrium of the contact force along the pile-soil contact face, the dynamic response equations of the single row of piles under an external circular time-harmonic surface vertical load are achieved. Then, the displacements at the observation point with and without the effect of piles are obtained, respectively. The influences of the soils' transverse isotropy, stratification characteristics and pile spacing on the isolation effect of the single row of piles are investigated.
