摘要
本文从桩端压缩层深度和桩端裂缝研究角度入手,分析了大直径桩基础桩端压缩层深度和桩端地基塑性流动对桩端裂缝填充的趋势,解释了大直径桩基础桩端阻力折减的原因,使用弹性地基Cook模型建立了桩端裂缝宽度计算公式。
From the researching of the depth of compress layer and the crack width around pile tip, this article analyzes the trend for the compress layer depth under pile tip and the filling action by plastic flows of soil, explains the reason of pile tip resistance reduction, and builds the calculation formula on the Cook＇s physical model of elastic soils.
