    Abstract

    Radiated waves from a laterally vibrating pile in a homogeneous-elastic soil layer as media within limits of small deformations are studied. It is shown that zero traction surface of soil layer together with fixed bedrock establish conditions which can only be satisfied via certain set of wave frequencies. It is shown that radiation of pressure waves closely related to the amount of vertical deformation induced in soil media due to lateral pile movements. Shear waves however, are radiated from pile independent from the vertical deformations. It is concluded that in cases of very smooth pile surface where relative vertical slippage between soil and pile skin may occur, the formation of P-waves might be limited. Complex valued amplitudes of shear and pressure waves radiated from a rigid circular pile under known lateral vibration is studied.
