Research on application of scour prevention technology for single pile foundation of offshore wind power
The water depth of the wind turbine foundation of the offshore wind power project in the deep sea is deep,and the ocean current erosion is strong.The single pile foundation of offshore wind turbine mostly used sand quilt or enrockment to prevent the erosion of the foundation root by the current.However,the scour prevention ability of conventional sand quilt construction technology was weak,and the construction precision of enrockment was not easy to control.Based on a wind field in the South China Sea,a study was conducted on the feasibility of the scour prevention of solidified soil for single pile foundation in deep sea offshore wind power project under complex sea conditions through the research of the scheme of solidified soil.The results show that the overall uniformity of the solidified soil material is good,the cohesion index is high,and the scour prevention ability is strong,which fits well with the single pile foundation.In terms of economy,the solidified soil scheme has high economy,compared to the sand quilt and enrockment.In terms of scour prevention effect,the solidified soil can realize the whole life cycle protection of single pile foundation,which can be popularized and applied in deep sea offshore wind power projects.
