Abstract

Soil anchors are generally used for structures that are subjected to pullout forces, such as offshore floating bodies, transmission towers, structures requiring lateral resistance or submerged platforms etc. Multi-plate anchors are used as a foundation that apply either large compression or tension forces using a number of plates welded along a central shaft. These anchors that have more than one plate have a complex interaction between the adjacent plates due to over applying stress zones. Therefore, this interaction affects the failure mechanism and the uplift capacity of the system. However, no thorough numerical analyses have been performed to determine the ultimate pullout loads of multi-plate anchors. By far the majority of the research has been directed towards the tensile uplift behavior of one-plate single anchor. Estimating the uplift capacity by using a practical design method that is obtained from a numerical analysis of two-plate anchors in sand is described in this paper. This method can be used more confidently by design engineers to estimate the pullout capacity of two-plate anchors under tension loading. The theoretical results are compared with the numerical data and acceptable values are obtained. G. Misir: Predicting the uplift capacity of vertically located two-plate anchors

垂直定位的两个板锚的抗拔能力预测

土锚一般用于受拉拔力的结构，如海上浮体、输电塔、需要侧向阻力的结构或水下平台等。多板锚被用作基础，使用沿中心轴焊接的许多板施加大的压缩或拉力。这些锚有一个以上的板块，有一个复杂的相互作用，相邻板块之间由于过度施加应力区。因此，这种相互作用影响了体系的破坏机制和上拔能力。然而，目前还没有进行全面的数值分析来确定多板锚的极限拉拔载荷。到目前为止，大多数研究都是针对单板锚杆的拉拔行为。本文通过对砂土中两板锚杆的数值分析，提出了一种实用的设计方法来估计锚杆的抗拔能力。该方法可以更可靠地用于设计工程师对两板锚在受拉荷载作用下的拉拔能力的估算。将理论结果与数值数据进行了比较，得到了可接受的数值。G.
