| 摘 要： | 针对以往预应力锚固单孔应力场计算时忽略小孔的影响，并将均布力用集中力来代替所造成的忽略应力集中现象的缺陷，提出了具有有限深孔的半无限弹性体，在孔周水平边界上作用有环形均布荷载时应力场的计算方法，为高吨位预应力锚固外锚头基础设计提供了理论依据。

| Abstract: | In the past, while calculating the stress field of a single hole fixed by a prestressing anchor, we used to ignore the hole's influence and the stress centering phenomenon, and assume uniformly distributed force. Aimed at this drawback, a novel method is proposed in this paper to compute the field for semi-infinite elastic solid with a finite depth hole and circular uniformly distributed load around its hotizontal boundaries, hence providing theoretical basis for the head design of high-tonnage prestressing anchors. |
