Abstract—Hybrid monopile-footing foundation, i.e., the addition of circular load-bearing plates at the mudline of large diameter offshore piles subjected to large horizontal-moment loads, is an innovative offshore structure. In this paper, the ultimate horizontal bearing capacity of hybrid monopile foundations is investigated by numerical simulation, in ABAQUS v6.14-1, using the small strain finite element method to simulate hybrid monopile-footing foundation subjected to lateral loads and to study the horizontal bearing performance of hybrid monopile-footing foundations in saturated soft clay soils with different circular footing foundation diameters. The Tresca model is used in this simulation and the validity of this simulation is verified by comparing the analysis with the theoretical and numerical solutions of circular footing foundations. The lateral load bearing performance of hybrid monopile foundations in soft clay soils is obtained by comparing and analysing the ultimate lateral bearing capacity for different circular footing foundation diameters.
Keywords—hybrid monopile-footing foundation, undrained capacity, numerical analysis
