CENTRIFUGE OF THE UNIVERSITY OF DELFT
Simulation of scouring ice keel on clay layer, performed at 5-10-2004
Aim: how large is soil deformation below keel.
Conditions:
Half 3D test at 100g, more or less undrained
Ice keel: width = 60mm (simulating 12 m prototype)
Scouring depth: 10 mm (is 1 m prototype)
Speed: 4mm/min
Clay: Cu=25kPa
Initial stage and the deformation in steady state conditions. Grid size = 5mm
Load displacement diagram during test. For real loads multiply with 20000
View at the soil surface.
View at the front of the keel
