摘　　要：海上风电单桩基础施工过程中,用于保证单桩沉桩垂直度的坐底式抱桩架和单桩会发生碰撞,这是由于浮吊船舶运动和环境力影响造成的。基于OrcaFlex软件对这一过程进行建模分析,对相关影响因素逐一排查汇总,给出碰撞破坏力的范围,找出降低碰撞力的施工要点,为后续的单桩施工提供理论支持并对抱桩架的设计建造提供数据支持。During the construction of a single pile foundation for offshore wind power,the bottom-sitting pile holder used to ensure the perpendicularity of a single pile will collide with a single pile,which is caused by the impact of floating crane ship movement and environmental forces.This paper,based on OrcaFlex software,conducts a modeling analysis of this process,checks and summarizes relevant influencing factors one by one,and gives the range of collision destructive force.The key points of reducing the collision force are found out to provide theoretical support for the subsequent single pile construction and data support for the design and construction of pile holder.
