摘要
本文简要回顾了国内外嵌岩挖孔桩的发展历程 ,指出这类桩现存的主要问题。讨论了嵌岩挖孔桩的工作性状及桩土共同作用 ,阐述了其所表现的主要特点。用弹性理论的方法分析了嵌岩情况下 ,挖孔桩桩身纵向弯曲变形对其沉降的影响 ,并结合一个具体的桩基工程实例进行验证。最后 ,介绍了嵌岩挖孔桩的结构特征 ,对这类桩的结构设计提出一些新建议。
This article looks back on the course of development in rock-embedding anchors both at home and abroad and points out the major existing issues thereof. It discuss the combined action between anchors and their soils and describes the key features it presents. Using elastic theory analyses the impacts of longitudinal curvature deformation on subsidence. Finally some new suggestions are made to this kind of design.
