摘要
基于真实设计参数和环境荷载,通过PLAXIS Monopile Designer和SACS软件实现某风场机位的缩径单桩优化设计,并进行结构极限强度、结构变形、自振频率和疲劳分析计算.相比于相同上部尺寸的常规单桩基础,缩径单桩具有较大的泥面转角和水平位移,较低的竖向位移和自振频率,计算结果验证了缩径单桩基础方案的可行性,并可实现节省10.9%的用钢量.
Abstract
Based on the real design parameters and environmental load,PLAXIS Monopile Designer and SACS software were used to realize the optimal design of reduced monopile in a wind field of China.The ultimate strength,structural deformation,natural vibration frequency and fatigue analysis were carried out.The reduced monopile with the same upper size had a larger mud surface angle and horizontal displacement,and a lower vertical displacement and natural vibration frequency.The results verify the feasibility of the reduced monopile scheme,and achieve a 10.9%reduction in steel consumption.
