With the offshore wind power from shallow sea to deep sea,fixed offshore platforms are gradually replaced by floating offshore platforms.As the fundamental part of a floating mooring system,the torpedo anchor foundation eliminates the installation-related drawbacks of a fixed mooring system,such as reliance on water depth,and serves as the"main force"of marine wind power to the deep sea.This paper used PLAXIS 3D finite element software to conduct a numerical simulation study of the torpedo anchor pull-out process to investigate the pull-out characteristics of torpedo anchor foundations.The pull-out displacement and torpedo anchor deformation were studied in relation to the torpedo anchor's ultimate penetration depth and inclination condition after it has penetrated the soil.The findings indicate that as penetration depth increases,the torpedo anchor's pullout displacement reduces.Additionally,the slant of torpedo anchors can effectively lower this pullout displacement.The research results can provide useful reference for the design and installation of torpedo anchor.
