摘　　要：[目的]海上风力发电因其年均发电量高和发电稳定等优势,逐渐在全球能源结构转型中得到广泛应用。然而,由于海上风机建设在复杂多变的海洋环境中,这给海上风机基础的施工工艺和技术方案带来了巨大的障碍。[方法]文章以某海上风电场的建设项目为背景,具体分析了沉桩施工船舶、稳桩平台和液压打桩锤的选型标准与可行性。同时依据风机基础沉桩的施工要求,重点阐述了作业前的准备工作、稳桩平台的施工方案以及主-副吊船协同配合的风机基础沉桩作业,并进一步分析了风机基础沉桩中垂直度的控制与纠偏措施。[结果]钢管桩沉桩施工工艺可以有效地保障工程质量和进度预期,经济效益明显且安全可靠。在沉桩过程中,需对垂直度精度控制完成初调和终调。[结论]对海上风机基础沉桩施工技术的研究,将为类似的海上风机工程提供有益的参考和借鉴。[Introduction]Offshore wind power generation is gradually being widely applied in the global energy structure transformation due to its advantages of high annual power generation and stable power generation.However,due to the complex and ever-changing marine environment for offshore wind turbine construction,this poses significant obstacles to the construction process and technical solutions of offshore wind turbine foundations.[Method]In the context of the construction project of a certain offshore wind farm,this paper analyzed the type selection criteria and feasibility of pile driving construction ships,pile stabilizing platforms and hydraulic pile hammers.At the same time,in response to the construction requirements for wind turbine foundation pile driving,the preparation work before the operation,the construction plan for the pile stabilizing platform,and the wind turbine foundation pile driving operation with the cooperation of the main-auxiliary crane ships were emphasized.Furthermore,the control and correction measures for verticality in wind turbine foundation pile driving were analyzed.[Result]Steel pipe pile driving construction process can effectively ensure the project quality and expected progress,and has significant economic benefits,safety and reliability.During the pile driving process,it's necessary to complete preliminary and final adjustments to the verticality accural control.[Conclusion]Through the study of pile driving construction technology for offshore wind turbine foundations,it will provide useful reference and inspiration for similar offshore wind turbine projects.
