Simulation of Dynamic Loading In Centrifuge Modeling For Suction Bucket Foundations

Suction bucket foundations are widely used in the offshore platform for the exploitation of the offshore petroleum and natural gas resources in the Bohai Bay of China. During winter seasons, ice sheets formed in Bohai Bay will impose strong impact and result in strong vibration on the platform. The measured frequency of the structural vibration of the platforms is 0.8 similar to 1.0 Hz. This paper describes a dynamic loading device developed on the geotechnical centrifuge at Tsinghua University and its application in modeling suction bucket foundation under the equivalent ice-induced vibration loadings.
