摘　　要：基于10 MW级大型风机,采用钢筋混凝土结构,进行了半潜浮式风机平台的概念设计,采用SESAM建立平台的数值模型,对立柱间距、立柱倾角及立柱直径对该半潜平台完整稳性的影响规律进行了重点研究并对平台进行优化,对优化后半潜平台的破舱稳性、综合许用重心高度及固有周期进行了验证。结果表明:以上因素以不同的方式影响平台完整稳性,而增加立柱倾角在钢筋混凝土用量和排水量等方面更具优势,优化后的平台完整稳性、破舱稳性、综合许用重心高度及运动周期均满足设计规范要求。Based on DTU 10 MW wind turbine,a reinforced concrete semisubmersible floating platform was designed in this paper.The influence of the distance between columns,the inclination and diameter of columns on intact stability of the semisubmersible platform was investigated and the design parameters of the platform was optimized by using the SESAM software.Meanwhile,damaged stability,integrated allowable vertical center of gravity(AVCG)and natural periods were verified.The results indicate that these factors affect stability in different ways and increasing inclination of columns is more advantageous in amount of reinforced concrete and displacement,and the optimized platform meets the requirements of intact stability,damaged stability,AVCG and natural periods.
