Abstract

Three-dimensional passive structural vibration isolation by rows of piles is studied numerically by the frequency domain boundary element method. The source of soil vibration is assumed to be a vertical force harmonically varying with time. The piles and the soil material behaviour are assumed to be linear elastic or viscoelastic. Coupling between the soil and piles is accomplished through equilibrium and compatibility at their interfaces. Both continuous and discontinuous quadratic quadrilateral elements are employed and advanced direct numerical integration schemes are used for the treatment of the various singular integrals. The full-space dynamic fundamental solution is used and this requires a discretization of not on
