Abstract:Bucket Foundation plate is a new type of offshore platform in recent years. It attracts much attention of oil companies and researchers in many countries by its merits. This paper reviews the progress on the suction penetration, instability of the foundations, the ice-induced vibration and the constitutive relation of soils under cyclic loading which are closely related with the analysis of instability of the foundations. At last, some problems under conditions of Bohai area needed to study in the future are presented, which include: the drag of sinking, the softening characteristics and the probabilities of liquefaction, appropriate dynamic constitutive relation of sand and numerical methods, experiments and modelling laws e.t.c.
Keywords:bucket foundations   suction penetration   ice-induced vibration   constitutive relation   offshore platform
