An advanced analytical procedure for a friction anchor-seabed interaction problem is developed to numerically estimate the dynamic response of a friction anchor with an end bearing plate due to mooring force of floating structure. In this paper, the friction anchor and the end bearing anchor plate are assumed to be an elastic rod and a flexible or rigid circular plate, respectively. The seabed is assumed to be a fluid-saturated poroelastic medium whose behavior is governed by Biot`s theory. The effects of the permeability of seabed, the radius and length of friction anchor on the dynamic response of it embedded in sea-bed are numerically investigated.
