摘要
确保海上风车基础的稳定且便于海上施工作业是吸力式海上风车基础设计的关键点.论文在分析影响筒基基础稳定性及海上施工难度的设计参数的基础上,建立了以吸力式筒基基础总重量与单筒直径的线性加权函数为目标函数、以单筒直径、入泥深度、筒体个数等参数为设计变量、以基础稳定性为约束条件的吸力式海上风车筒基基础优化设计模型,并将相对差商法的数学优化方法应用于该模型.文中建立的评估模型对其它筒基基础方案设计具有参考价值.
the key points in the design of offshore windturbine foundation are insuring stability of the foundation and convenience of construction at sea.Based on stability of the foundation and design factors of operating difficulty,establish the target which is linear weighted by the overall weight of the foundation and diameter of the single cylinder,choose diameter of the single cylinder,driving depth,the number of the tubes and so on,as the design variables,use stability of the foundation as constrain condition,at the same time,the relative difference quotient method is adopted to optimized the above mentioned model.The evaluation models have some reference value for other design of the tubes.
