Abstract:Though bucket foundation used as a new type of foundation in shallow water can have significant advantages over conventional ones, the bearing mechanism and failure model are still unclear under horizontal loads, especially for the complicated interaction between the structure and the soil. So the horizontal bearing capacity of single-bucket foundation is calculated based on three-dimensional finite element method. Compared with the model test, the numerical simulation is reliable. Then, a series of parametric comparative studies are carried out and it is found that the horizontal bearing capacity of single-bucket foundation in saturated soft clay ground increases with the increasing of soil effective unit weight, soil deformation modulus and bucket slenderness ratio, but reduces with the increasing of loading height, from which some suggestions are given for engineering practice.
