摘　　要：海上风电工程多采用高桩承台结构,其中桩基多为大直径钢管桩。在正式工程开工前需要进行试桩工程对桩基设计参数进行确认,并进行相应的优化。由于外海自然环境恶劣,采用常规的试验方法无法满足工程需求。通过改进测试方法、增加测试项目、改造试验装备,提高了传统试验方法的可靠性,可确保恶劣自然环境下试验的开展,确保试验数据准确、可靠,通过工程应用取得了良好的应用效果。High-piled foundation was one of the most common forms of offshore wind power project and the pile foundations are mostly large diameter steel pipe piles.It is necessary to confirm the design parameters of pile foundation and optimize the structure before the formal project starts.Because of the adverse environmental circumstance in offshore areas,the general testing method can not meet the engineering requirements.Based on the improvement of testing methods,adding test items and revamping test equipment,the reliability of general testing method was improved and the test data in adverse environmental circumstance was ensured to be accurate and reliable.Good application results are obtained through engineering application.
