Abstract

In this paper, the seepage field characteristics of multi-cell bucket foundation are studied under the condition that the middle cell pressure is less than the side cell pressure. The influence of cell pressure ratio and middle cell size on critical suction was analyzed, and the calculation method of the critical suction taking into account cell pressure ratio and middle cell size was established. Based on the principle of effective stress, a calculation method of required suctionfor the multi-cell bucket foundation was established, and the effect of middle cell size on suction drag reduction was analyzed.

Key words

offshore wind pewer / bucket foundation / critical suction / required suction / cell pressure ratio / middle cell relative dimension
