The study of bearing characteristics of gravity penetration column anchor for offshore floating turbine
摘要
Abstract
In the construction of floating wind farms,various soil conditions may be faced.Based on the needs in practice,a kind of anchor named gravity penetration column anchor is proposed for the soil with high permeability,where has high risk of installation by suction.The finite element method was used to analyze the penetration process and bearing characteristics of this kind of anchor.The analysis results show that in the coarse sand,the gravity penetration column anchor can penetrate to the design depth by its own weight.Unlike ordinary gravity anchors,which mainly provide anti sliding force through friction at the anchor bottom,the gravity penetration column anchor is shallow failure under horizontal load,and can mobilize more soil resistance during the failure improving its anti sliding ability effectively.The gravity penetration column anchor can provide a horizontal bearing capacity of more than 2 000 t,which is nearly twice that of conventional gravity anchors,and can meet the bearing requirements of floating wind turbine.This kind of anchor could provide more choices for offshore floatingturbine in China.关键词
