摘要： 海上风电基础承载装备的结构越来越复杂且越来越重，建造工艺与建造路径等不同会导致其残余应力不同，从而影响其安全性和可靠性。为此，基于有限元分析方法，分别采用梁单元与壳单元建立了不同的海上风电导管架计算模型，并运用单元生死技术模拟海上风电导管架的立式与卧式陆地建造过程。由模拟结果可知：使用壳单元能够更加准确地模拟海上风电导管架管件连接处的应力状态；采用立式建造工艺能够减小建造过程中海上风电导管架重点部位的应力并保持其稳定，且建造完成后海上风电导管架的残余应力更小。研究表明，大型海工结构的重点部位应使用能够反映实际结构特征的壳单元进行模拟，在陆地建造过程中立式建造工艺更为安全，这可为海上风电基础承载装备陆地建造工艺的选择提供依据。
Abstract: The structure of offshore wind power foundation bearing equipment becomes more and more complex and heavier. Different construction processes and construction paths will lead to different residual stresses of the bearing equipment, which will affect its safety and reliability. Therefore, based on the finite element analysis method, different calculation models of offshore wind power jacket were established by using the beam element and the shell element, respectively. Then, the vertical and horizontal on-land construction processes of the offshore wind power jacket were simulated by using the element life-and-death technology. The simulation results showed that the shell element could simulate the stress state at the connections of offshore wind power jacket pipes more accurately; vertical construction process could reduce the residual stress on the key parts of the offshore wind power jacket and keep it stable during the construction, and the residual stress of the offshore wind power jacket was smaller after the construction was completed. The research results show that the key parts of large offshore structures should be simulated by shell elements which can reflect the actual structural characteristics, and the vertical construction process is safer during the on-land construction, which can provide a reference for the selection of on-land construction process for the offshore wind power foundation bearing equipment.
