Suction caissons have increasingly been used as foundations and anchors for deepwater offshore structures in the last decade. The increased use of suction caissons defines a serious need to develop more authentic methods for simulating their behavior. Reliable assessment of uplift capacity of caissons in cohesive soils is a critical issue facing design engineers. This paper proposes a new approach for the formulation of the uplift capacity of suction caissons using a promising variant of Genetic Programming (GP), namely Multi Expression Programming (MEP). The proposed model is developed based on experimental results obtained from the literature. The derived MEP-based formula takes into account the effect of aspect ratio of caisson, shear strength of clayey soil, point of application and angle of inclination of loading, soil permeability and loading rate. A subsequent parametric analysis is carried out and the trends of the results are confirmed via previous studies. The results indicate that the MEP formulation can predict the uplift capacity of suction caissons with an acceptable level of accuracy. The proposed formula provides a prediction performance better than or comparable with the models found in the literature. The MEP-based simplified formulation is particularly valuable for providing an analysis tool accessible to practicing engineers.

“…The resisting moment mobilized at the tip of the rotating caisson, M b0 , can be computed by evaluating by appropriate integration over the area of the spherical failure surface (Murff and Hamilton, 1993). In a simplified approach, Aubeny et al (2003c) perform the necessary integration to obtain an empirical relation of the form:…”

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 threedimensional 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.
