摘　　要：将灌注端承桩受竖向荷载时的荷载与位移的关系曲线运用于突变理论,导出了单桩竖向承载力的计算公式,给出了延性破坏与脆性破坏的界定标准,为其进一步的分析研究提供了理论基础。It applies the relation curve of load and displacement of the cast in place end bearing the vertical loading to the mutation theory, deduces the calculating formula of single vertical bearing, gives the definition standard of ductility damage and brittlement damage, and gives the theory basis to the further analysis and research.

关 键 词：单桩竖向承载力 稳定性分析 突变理论 尖点突变
