摘　　要：以两个工程实例,对高压旋喷桩大量的实测受力数据进行统计分析计算,得到高压旋喷桩水泥土抗压强度平均值、桩身强度在不同土层的分布范围和单桩极限承载力的理论值,且对统计分析计算结果与现场载荷试验结果、桩身受力分布规律进行了对比分析.From the statistical analysis of the observed data of stressed state of the high pressure churning piles in two projects,obtained are the average value of the compression strength of the cement-soil base,the strengths of the pile stem performed at the different layers of the cement-soil,and the theoretical ultimate bearing stress of a single pile.A comparison is made between these results and the on-site load test results,and between these results and the regularity of the stress distribution of the pile stem.

关 键 词：高压旋喷桩 统计计算方法 载荷试验 桩身受力分布.
