Horizontal vibration of a cylindrical rigid foundation embedded in poroelastic half-space

Abstract

This paper presents an analytical solution that describes the response of a cylindrical rigid foundation embedded in poroelastic soil to a horizontal harmonic load. The soil underlying the foundation base is modelled as homogeneous poroelastic half-space while the soil around the shaft of the cylindrical foundation is modelled as a series of infinitesimally thin poroelastic layers. Using the proposed solution we investigate how the dynamic interaction of the foundation with its surrounding poroelastic soil is affected by the geometry and mass of the foundation, as well as the properties of the soil surrounding the shaft and underlying the foundation base.
