... in the center, hosting rubble, to be placed behind the caisson. The rubbles in the hole are well interlocked with the lower rubble mound layer, and therefore effectively contribute to the sliding resistance of the caisson. A series of 3d experiment under irregular waves are carried out, testing different design...

... The purpose of the model tests performed in the Ice Tank of Krylov Institute, St.Petersburg, Russia, was to study the effect of the closeness of the sea bottom on the ice pile-up in front of the Caisson-Type platform and on ice loads acting onto the platform. Grounding of the ice rubble can lead...
