GU Shi-tan, SHI Jian-yong, WANG Chun-qiu, et al. Theoretical study of core pile load transfer regularity of reinforced mixing pile[J]. 2011, 32(8).DOI:
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.
