Analysis of Bearing Characteristics of Single Pile Based on the Axial Force Distribution Function

Liang Jinguo, Ding Jihui, Liu Hongchao

2015, 29(6): 306-310,323. doi: 10.3969/j.issn.1007-2993.2015.06.006

[Abstract](84) [PDF 1289KB](13)

Abstract:
Based on the attenuation law of the pile axial force with the buried depth of piles under the vertical load,the expression of the axial force distribution function of pile section is proposed and is related to the ratio of the length to diameter ratio of the pile and the Share ratio of the tip.The b...
