Abstract

Suction caissons are used widely for anchoring floating facilities in deep waters, and as foundations for supporting wind turbin s in shallow water regions. The behaviour of a stiffened caisson anchor during installation, monotonic pullout and cyclic loading in lightly overconsolidated calcareous silt were firstly investigated through a series of centrifuge tests. Numerical simulations
of caisson installation and post-installation set-up were then carried out to determine a normalised dissipation time around caissons. The effectiveness of sand/gravel blanket to optimise the capacity of a caisson foundation subjected to monotonic and cyclic loadings in layered sand-clay-sand deposit was lastly explored through centrifuge tests.
