The Influence Of The Loop Of Shearing Soil To The Seepage Field Suction Anchor During Suction Penetration

Suction anchor is a new style of offshore platform foundation. The loop ofshearing soil is the key problem during the process of suction penetration of suctionanchor in construction. By finite element method analysis of seepage field of suctionanchor .By the finite element software of ANSYS simulating soil around the anchor.The results of analysis decided the influence of the loop of shearing soil to seepagefield.During the construction of suction anchor by suction penetration, with the depthof penetration, the side friction of suction anchor is increasing. When the side frictionup to certain number, and the friction will prevent the penetrating of suction anchor inadvance. The loop of shearing soil installation will avoid the phenomena. The effectof the loop of shearing soil is reducing side friction. The paper studies the influence ofthe loop of shearing soil installation to seepage field, the influence of the size of theloop of shearing soil and the location of the loop of shearing soil to seepage field bythe software ANSYS.The research of the loop of shearing soil is a meaningful reference for the suctioncontrol during the process of suction penetration and the suction anchor's design andconstruction.
