导管支架基础和单桩相结合的新型复合风电基础
A new composite wind turbine foundation combining the jacket and monopile foundations
摘要
Abstract
In view of the lack of lateral stiffness of the monopile and in order to improve the applicability of it, this paper proposes a new wind turbine foundation which is based on a monopile and supplemented by a jacket founda-tion. By using the general finite element program ABAQUS, and taking the 3 MW turbine foundation as the research object, a finite element model is created to simulate the stress process of the monopile and the new composite foun-dation respectively in the sandy and silt-filled clay soil, and analyze the new composite foundation stress;and using the diameter and depth of the three structural-piles of the jacket as variables, the stress and the levelness variation of the new composite foundation are researched. The calculation results show that:with the structural-pile's diame-ter and depth increasing, the stress of the main pile above the jacket in the new composite foundation is basically unchanged, but the stress of the pile next to the surface and the levelness of the pile are obviously reduced; and with the depth increasing, the increase of the steel consumption amount is smaller, but the stress of the main pile next to the soil surface and the levelness of the pile are reduced to a great extent. These findings will provide some reference for structural optimization.关键词
