In response to the problem of traditional large-diameter type Ⅲ rock socketed monopile construction for offshore wind farms being affected by harsh geological conditions and uncontrollable cost and construction period,taking a wind farm in Fujian as an example,the feasibility of applying high-pressure rotating jet grouting technology in large-diameter rock socketed monopile construction is analyzed.The actual application and theoretical calculation analysis results show that with the support of appropriate geological and high-pressure rotation jet grouting technology,the type Ⅲ monopile can be successfully transformed into a directly driven type Ⅰ pile foundation,which can effectively shorten the construction period and save construction costs.The research results can provide reference for the construction optimization of such type Ⅲ rock socketed monopiles.
