摘　　要：海上风电建设是我国绿色低碳战略的重要组成部分,海上风电超大直径钢管桩作为一种主流的海上风电基础结构形式,其结构质量检测对海上风电基础结构安全有着至关重要的作用。以海上风电超大直径钢管桩为对象,进行钢管桩结构质量智能化检测的研究与应用,采用激光扫描仪获取成型钢管桩的点云数据,通过点云数据过滤与降噪、点云数据特征提取、点云数据配准与融合等步骤,将点云数据进行拟合生成三维数字模型,结合钢管桩BIM设计模型进行计算与分析,得出钢管桩直线度、管端平整度、管和桩顶法兰之间的垂直度等关键结构质量参数,为超大直径钢管桩生产质量控制提供重要支撑。Offshore wind power construction is an important part of China’s low-carbon green strategy.As a mainstream form of offshore wind power infrastructure,the structural quality inspection of offshore wind power super-large diameter steel pipe piles plays a vital role in the safety of offshore wind power infrastructure.Taking the super-large diameter steel pipe piles of offshore wind power as the object,the research and application of intelligent detection of steel pipe pile structure quality are implemented.The laser scanner was used to obtain the point cloud data of the formed steel pipe pile.Through the steps of point cloud data filtering and noise reduction,point cloud data feature extraction,point cloud data registration and fusion,etc.,the point cloud data were fitted to generate a three-dimensional digital model.Combined with the BIM design model of steel pipe pile,the calculation and analysis were carried out,and the key structural quality parameters such as the straightness of the pipe pile,the flatness of the pipe end,and the verticality between pipe and pile top flange were obtained,which provides important support for the production quality control of super-large diameter steel pipe pile.
