摘　　要：近年来,海上风电场已经成为改善能源结构和开发、利用海洋资源的有效途径。海上风电场建设前,需要进行详细的地形测量,以查明待建区的陆地地形、海域水深和海底障碍物分布情况等。海上风电场地形测量包括陆地地形测量和海上地形测量两部分,需要根据海上风电场测区特点,研究制定合适的测绘方法。本文以实际工程为例,研究了海上风电场地形测绘方法,并结合实时动态载波相位差分技术(RTK)测量、单波束测量和多波束测量的技术特点,制定了从陆地到海洋的测绘方案和技术流程,获取了海上风电场三维地形图。精度分析结果表明,本文所用方法科学、有效,可为相关工程应用提供参考。In recent years,offshore wind farms have become an effective way to improve energy structure and develop and utilize marine resources.Before the construction of offshore wind farms,detailed topo⁃graphic surveys are required to determine the land topography,the water depth of the sea area and the distribution of seabed obstacles in the area to be constructed.The topographic survey of offshore wind farms includes land topographic survey and offshore topographic survey.Therefore,suitable surveying and mapping methods should be studied and developed according to the characteristics of the surveyed area of offshore wind farms.Taking practical engineering as an example,this paper studies the topographic mapping method of offshore wind farms,and combines the technical characteristics of RTK measurement,singlebeam measurement and multibeam measurement to formulate a landtoocean measurement plan and technical process,and gets the 3D topographic map of the offshore wind farm.The accuracy analysis results show that the method used in this paper is scientific and effective,it can provide helpful reference for related engineering applications.
