Vertical Bearing Capacity

Recently,ocean energy, especially wind energy, gains attention from all over the world.In offshore engineering , the design and construction of foundation are key factors. As a new type of piles, screw pile has advantages of compressive capacity and uplift capacity.Therefore, screw pile is a good choice for offshore engineering foundation. In this paper , ABAQUS software analysed vertical bearing capacity of screw pile and steel pile with same diameter in clay .And the analysis result shows : the compressive resistance and uplift resistance of screw pile are 1104KN and 974.3KN, the same capacity of steel pile are only 332.3KN and 189.7KN.

Vertical Bearing Capacity

As a new type of deep water offshore foundation, suction caisson is widely used to offshore structures. However, the current methods of evaluation and design cannot meet the increasing requirement of engineering practice. In this dissertation, the studies are emphasized on finite element method for analyzing the suction caisson bearing capacity behavior and the failure mechanism under the vertical load. Based on studying the vertical bearing behavior of caissons with different ratio of length to diameter L / D, it shown that as L / D increases, the vertical bearing capacity growth slowed.
