摘　　要：针对施工过程中海上风机高桩承台基础封底混凝土与钢管桩间黏结力不足以满足承台受力要求的问题,在钢管桩周围增设剪力件,设计多组剪力件方案,采用有限元软件ANSYS分别对包含不同剪力件的整体结构进行建模,计算剪力件、承台、钢管桩等的受力,对比不同方案的计算结果,分析得到最佳设计方案。In order to solve the problem that the bonding force between the bottoming concrete and steel pipe piles of foundation of high pile cap of offshore wind turbines during construction cannot satisfy the capacity of cap,the method of welding reinforced shear members around the steel pipe piles was adopted.Several schemes of shear members were designed.Models of the whole structure with different shear members were established in ANSYS to calculate the forces of shear members,caps and steel pipe piles.The numerical results were compared and analyzed,so as to obtain the best design scheme.
