摘要:
法向承力锚(VLA)是一种新型深海工程系泊基础,锚板的极限抗拔力是反映其工作性能的主要指标.基于假设海底软黏土为符合Mises 屈服准则的理想弹塑性材料以及锚板为一刚性体,采用大型有限元软件ABAQUS 建立二维有限元模型,利用接触对模拟锚板与周围土体间的相互作用.从锚板粗糙程度、埋置深度、埋置角度、宽厚比以及荷载作用位置等多角度研究影响VLA 极限抗拔力的因素及其影响规律.结果表明:当锚板埋深较小时,法向承载力系数随着锚板埋深和埋置角度增加而逐渐增大;当法向荷载作用在锚板形心处时其法向承载力系数大于法向荷载作用在非形心处时的法向承载力系数.
Abstract:
Vertically loaded anchor(VLA)is a new type of mooring foundation for deep-water offshore engineering.The ultimate pull-out capacity of anchor plate is an important working performance parameter. Based on the assumption that submarine soft soil around anchor plate is an elastic-perfectly plastic material which obeys Mises yield condition,
and the anchor plate is a rigid body,the two-dimensional finite element model is established by use of the finite element analysis software ABAQUS and the anchor-soil interaction is simulated by the contact pair. Moreover,many influencing factors including oughness,embedment depth,inclination angle,aspect ratio,and load position of anchor plate are considered to analyze the ultimate pull-out capacity of VLA. It’s found that at a shallow embedment depth,the normal bearing capacity factor increases with increasing embedment depth and inclination angle of the anchor. The normal bearing capacity factor which normal load acts on anchor’s centroid of area is larger than that the load is not at the centroid of area.
