碎石桩的塑性分析及极限承载力计算

以土力学及弹塑性理论为基础，在适当的假定基础上，分析了碎石桩的塑料性应力分布，并推导出了单桩极限承载力和单桩复合地基的极限承载力计算公式，得出了单桩静载试验结果无法反映碎石桩复合地基中桩柱体的承载能力的结论，章最后出了一个工程实例，以验证本的计算公式。

PLASTICS ANALYSIS AND BEARING CAPACITY ON THE STONE PILE

In this paper. Based on the soil mechanics and the elastic and plastics theory.By means of some hypothesis, the distribution of the plastics stress on the stone pile is analysed.And the Calculating formulations on the ultimate bearing capacity of the single pile and single pile with composite foundation are derived.And indicating the result of the static test on the single pile can't reflect bearing capacity of pile in the composite foundation of the stone pile. At the end of this paper, An engineering example is discussed to test and verify these formulation.
