摘要：

The flexibility matrices of transversely isotropic saturated viscoelastic soils are obtained by the extended precise integration method. We use the finite element method (FEM) to derive the stiffness matrix of pile. The pile-soil interface is divided into elements corresponding to the pile elements based on the boundary element method (BEM). The pile-soil interaction equation is established by the coupling of FEM and BEM. The solutions for the equation are achieved by combining the compatibility condition between the pile and the soil. Numerical examples are presented to study the influences of soil and pile properties on the time-dependent behaviour of piles.
