Shaking Table Test of Liquefiable Site-Bucket Foundation-Offshore Wind Turbine Structure Seismic Response
In order to explore the dynamic response of the superstructure and the deformation characteristics of the site after sand liquefaction of offshore wind turbine foundation under the combined action of wind, wave and earthquake, a large-scale shaking table test of offshore wind turbine suction bucket considering the combined load of wind and wave. According to the research objective and purpose, this paper expounds the overall design scheme of the test, the design and preparation of the site and structure, the selection and layout of the sensor, and the selection and working conditions of the wind, wave and seismic load. The test results show that under the action of 0.35 g EL Centro wave, the saturated sand site is completely liquefied, the site loses its bearing capacity, the single bucket foundation is inclined and pulled out, and the bucket foundation is completely invalid. In this paper, the variation law of pore pressure and acceleration after liquefaction of saturated sand site is analyzed. This experiment has achieved the expected goal, indicating that the series of experimental design is reasonable.
