Abstract
The traditional bucket foundation use vertical wall, which like a cup is buried upside down in seabed. A new bucket foundation with partial inclined wall has been proposed in this article. Based on limit equilibrium analysis of three-dimensional stress state of foundation, the calculation method of the horizontal bearing capacity of the new bucket foundation has been deduced, which has been verified by model tests. It is found that the horizontal bearing capacity of the new bucket foundation increased effectively when dip angle of wall is increased. The horizontal bearing capacity of the new bucket foundation increased with the proportional coefficient of horizontal subgrade reaction, top diameter or height of bucket foundation increased respectively, while it decreased when the depth of seabed was increased. The parameters of the new bucket foundation should be determined by geological conditions of seabed, physical and mechanical parameters of marine soil, design value of horizontal bearing capacity and construction method. The research results would be conducive to optimize design of traditional bucket foundation.
