Abstract Suction bucket foundations for offshore wind turbines (OWT) have considerable advantages compared to conventional foundation types: Due to the installation process with dead weight and applied negative pressure, noise from pile driving can be completely avoided. In addition, the installation process of the whole substructure, consisting of the buckets connected to the jacket, can be carried out in one work step, which increases efficiency. A prototype of the suction bucket jacket was installed in the wind park ‘Borkum Riffgrund 1’ (North Sea) in August 2014. Due to the pre-installed and comprehensive measuring system, it was possible to monitor all installation and operating phases. The data analysis of a storm event show an amplitude and frequency-dependent behaviour of the soil stiffness and the suction bucket foundation without wind turbine. In the frequency range of the first and second eigenfrequency (0.2 Hz

监测海上风力涡轮机的吸水桶夹套：动态承载行为和建模

摘要 海上风力发电机吸水桶基础（OWT）与传统基础类型相比具有相当大的优势：由于安装过程有自重和施加负压，可以完全避免打桩噪音。此外，整个下部结构的安装过程，包括连接到夹套的铲斗，可以在一个工作步骤中进行，从而提高了效率。2014 年 8 月，在风电场“Borkum Riffgrund 1”（北海）中安装了吸水桶外套的原型。由于预安装的综合测量系统，可以监控所有安装和运行阶段。风暴事件的数据分析显示了土壤刚度和没有风力涡轮机的吸力桶基础的幅度和频率相关行为。在第一和第二特征频率 (0.2 Hz) 的频率范围内
