Abstract

In this paper, the influential design factors of wide-shallow composite bucket foundation for 3 MW offshore wind turbine are systematically studied by numerical simulation. The results show that the bucket diameter is larger than 27 m in general, and the range of 7–12 m is appropriate for cylinder height. In particular, the bucket foundation with diameter of 30 m and cylinder height of 10 m is suitable for most soils. Under ultimate loads, the bucket diameter and elasticity modulus of soil have major effects on the deformability of bucket foundation, while the influence of friction coefficient between the bucket and soil is relatively slight.
