摘要
本文介绍了一种在圆形滑腔里进行的单桩模型试验,以模拟大规模带桩筏基的性状。文中提出了群桩地基破坏模式的理论判据,并推导出群桩地基极限承载力的计算公式。该公式反映出群桩间距对极限承载力的影响。
In this paper, a model test method that imitates the behaviour of a large-scale piled raft foundation by a single pile in circular slithery cavity is described, and a theoretical criterions for judging the failure mechanisms of pile tip is presented. A formula for calculating the ultimate bearing capacity of pile tip is derived. It is showed that the pile spacing has a great influence on the ultimate bearing capacity of pile tip.
