Suction piles have been widely used for offshore structures such as the foundations of subsea structures and the anchors for floating facilities particularly in soft soils. In previous studies, the penetration ratio L/D (L=embedded length, D=diameter) of suction piles has been taken from 0.25 to 1.0, and the behaviour of suction piles has been assumed to be similar to one of shallow foundations. However, in recent projects, the penetration ratio of suction piles is larger than 1.0 for the supports of large structures installed in clay. In this study, the vertical bearing capacity and ground failure mechanism is investigated using the Finite Element analysis(FE analysis) for suction piles installed in clay mainly subjected to the vertical load. The penetration ratio has the range of 0.25 to 5.0. The FE analysis results show that the penetration ratio gives a substantial effect on the vertical bearing capacity and the ground failure mechanism. The FE analysis results are compared with theoretical solutions. As the results of the comparison for the vertical bearing capacity, it is found that Prandtle’s theoretical solution is the most similar to the FE analysis results for the penetration ratio in the range of 0.25 to 1.0 and Meyerhof’s theoretical solution is the most similar to the FE analysis results for penetration ratio in the range of 3.0 to 5.0.
