摘要
为了研究海上风电三筒导管架基础在海洋土中的承载性能,文章对其在复合加载模式下的破坏包络线进行了探究,绘制了两种不同长径比三筒导管架基础的三维承载能力包络面,对比了极限工况下两种基础法兰及导管架处的倾斜率。结果表明:一定范围内的竖向荷载提高了基础的水平及弯矩极限承载力;三吸力筒式导管架基础的承载性能要略优于三吸力桩式导管架基础,且两者在不同荷载作用下的承载模式略有不同。总体而言,基础直径较大、筒高较小的三吸力筒导管架基础的承载性能要更强。
In the composite loading mode, the destroying envelope of the two three-bucket jacket foundations was explored, and two basic three-dimensional load-carrying capacity envelope were drawn, and the inclination rates of two kinds of foundation flanges and jackets under extreme working conditions are compared. The results show that in a certain range, the existence of vertical load improves the horizontal and moment ultimate bearing capacity of the foundation;and the bearing capacity of three-tube-jacket foundation is slightly better than that of three-pile-jacket foundation,and their bearing modes are slightly different under different loads. Overall, the carrying performance of the three-absorbing tube bracket base in the base diameter is stronger.
