Abstract


Suction Penetration sinking sea suction anchor foundation form the basis of study of this new offshore platform facing the suction anchor set shear the soil ring and shear soil ring its seepage field , seepage field by suction anchor finite element analysis software ANSYS finite element modeling and analysis of the the anchor body surrounding soil seepage field , the results calculated using the finite element analysis of shear soil ring seepage field . Suction anchor Shen anchor construction , buried depth increases , the anchor body suffered the greater lateral friction reaches a certain level , will result in the suction anchor can not continue to sink . To avoid this from happening , in the actual construction is usually provided on the anchor body scissors Soil ring to reduce the side friction of the impact . The paper, scissors the soil ring set seepage field , the shear the soil ring the size of the seepage field , cut the the soil ring position of the seepage field of impact , shear earth ring layered soil seepage field analysis research . In the calculation of an earthy circumstances , and considering the other two soil modeling analysis using ANSYS software , get the shear the soil ring on suction anchor sinking the sphere of influence of the seepage field , size , and degree of suction penetration . This paper studies the suction anchor Suction Penetration the soil ring settings and basic design and construction of the suction anchor under shear have some significance .
