| 摘 要： | 针对国内海上风电基础设计没有统一的规范及标准，为提升海上风电基础设计建设的水平，通过对东南沿海某海域海上风电基础的设计进行了有限元计算分析论证，验证了群桩高承台结构设计方案的设计方法和设计参数。分析结果表明该设计的最大应力主要发生在塔筒底座与承台接触部位及钢管桩与承台连接段，应在连接部位加强措施处理；基础竖直位移较小，水平位移相对较大；分界部位应力较集中，刚度不能顺畅过渡，可考虑填充碎石土等方法加强。本研究对海上风电基础设计技术的研究与探索，可为将来制定中国海上风电行业标准提供可靠的依据，对中国未来大批量的海上风电能源的开发有着重要意义。

| Abstract: | Wind power generation is an important aspect of renewable energy. With the advancement of green technology, offshore wind power has become a novel engineering hot spot in recent years. The main problems that remain to be solved are the design and of offshore wind energy facilities themselves. Offshore wind energy technology in European countries, where it developed relatively quickly, is the most often used reference in China; however, China currently depends on the design and construction standards used in hydropower construction and on offshore oil-drilling platforms, and offshore wind power standards are as yet unformed. After finite element calculation analysis and demonstration with the design of an offshore wind electron platform, the methods and parameters of design can be verified. Technological research and practical exploration of offshore wind farm can provide a reliable basis for making Chinese offshore wind electron the industry standard, and it will be of important value for the exploitation of mass offshore wind energy in the future in China. |
