摘要

劲性搅拌桩是一种典型的复合材料桩，基于复合材料力学原理及明德林位移解，对劲性搅拌桩中芯桩轴向应力、水泥土桩-芯桩界面剪应力进行理论分析，得到了劲性搅拌桩芯桩轴向应力、界面剪应力的分布规律，并与现场试验结果进行对比分析，结果表明：该理论分析结果与现场试验结果规律是一致的，可与试验结果互为验证，对于分析劲性搅拌桩的工作机制具有一定的理论价值。

Abstract

Reinforced mixing pile is a typical composite material pile; theoretical analysis of core pile axial stress and cement soil pile-core pile interface shear stress of reinforced mixing pile are carried out based on composite material mechanics and Mindlin displacement solution. Regularities of distribution of core pile axial stress and interface shear stress are deduced; theoretical results are compared with field test results. The comparison results show that theoretical analysis results are accordant with field test results and they can be verified each other. Theoretical study has significant value for analysis of performance mechanism of reinforced mixing pile.
