摘　　要：东海大桥海上风电场是亚洲第一座大型海上风电场,预计年上网电量2.67亿度电,可以满足上海市40万人口的用电需求。结合东海大桥海上风电场的场地地质勘测资料,依据德国劳埃德船级社规范及国内相关规范,设计了两种基础型式,即单桩基础和三脚架基础;而后,利用ANSYS软件分析了这两种基础型式的承载性能,对比了这两种基础型式的优劣,为海上风电场基础型式的选择提供参考。本文的工作为近海风机基础有限元分析提供了一个完整的范例。East China Sea Bridge offshore wind farm is the first offshore wind farm in Asia,the expected electric quantity for the network of which is 2. 67 hundred millions of kilowatt-hours,it can satisfy the utilization demand of 400 thousands of populations. In this article,according to GL and the related domestic codes,the author firstly designs two kinds of foundations based on the geological exploration data,namely,monopile and tripod,then the author contrasts the load-carrying property and quality of these two foundations by use of ANSYS,which can be referred in the foundation lectotype of offshore wind farm. This article can also be one intact example for the offshore wind turbine foundation finite element analysis.
