Frequency Response of Seabed around Anchor due to Steady-State Mooring Force

Abstract

In the analysis of soil-structure interaction problems, the ground is typically modelled by either an elastic or a visco-elastic medium.
It may be more suitable. however, to assume a fluid-filled porous material for seabed.
The frequency response of seabed around an end bearing anchor due to steady-state mooring force is numerically evaluated by assuming the seabed as a fluid-saturated poroelastic halfspace whose behavior is governed by Biot's theory, and depends on the permeability of seabed and the load carrying share of pore fluid to acting force.
In this paper, these effects to frequency response of seabed are investigated through some numerical examples.
