新型海上风电基础地基冲刷深度试验研究及床面剪切力分析
Experimental investigation of scour depth and bed shear force of new offshore wind power foundation
摘要
Abstract
Under the action of ocean environment,significant scour will occur around the seabed of offshore wind turbine foundations.If the scour depth is too large,it will seriously affect the safety of the wind turbine structure system.The composite bucket foundation is a new type of shallow foundation,which is more sensitive to scour.Taking the new offshore wind power composite bucket foundation as the research object,a physical model experiment of the foundation's surrounding scour characteristics under wave and current action was carried out.The scour variation characteristics and maximum scour depth of the seabed around the foundation was investigated.Based on the numerical model of wave-current with composite bucket foundation and soil,the distribution characteristics of bed shear force on the seabed surface were analyzed,and the correlation between the maximum scour depth and bed shear force was examined.The research results show that under the action of waves and currents,the maximum scour depth of the composite bucket foundation is located behind the foundation and adjacent to the foundation.The maximum scour depth decreases with the decrease of wave height,period,and flow velocity.The maximum scour depth of the seabed around the foundation has a certain correlation with the distribution of its maximum bed shear stress.关键词
