摘　　要：随着海洋风电由浅海走向深海,固定式海洋平台逐渐被漂浮式海洋平台取代。鱼雷锚基础作为漂浮式锚泊系统的基础部件,克服了固定式锚泊系统在安装过程中依赖水深等特点,成为海洋风电走向深海的“主力军”。为研究鱼雷锚基础的拉拔特性,本文基于PLAXIS 3D有限元软件开展了鱼雷锚拉拔过程的数值模拟研究,分析了鱼雷锚贯入土体后的最终贯入深度、倾斜状态对拉拔位移和鱼雷锚变形的影响规律。研究结果表明,鱼雷锚的拉拔位移随贯入深度的增加而减小,并且对鱼雷锚进行倾斜可有效减小鱼雷锚的拉拔位移。该研究成果可为鱼雷锚的设计和安装提供有益的借鉴与参考。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 pullout 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.
