变截面桩承载特性的研究综述

Research on loading characteristics of piles with variable sections

指出变截面桩具有承载性能高、节约材料、施工简便等特点,越来越多的应用在土木工程中,总结了挤扩支盘桩、扩底桩和钉形桩等几种变截面桩在桩基工程和地基处理工程中的应用特点,以完善变截面桩的设计与施工。

The paper points out the pile with variable sections has the advantages of high loading capacity, the material-saving and the convenient construction, so it is increasingly applied in civil engineering, sums up the application characteristics of some piles with variable sections in pile foundation project and foundation treatment project, such as the squeezed branch pile, the pedestal pile and the spike-shaped pile, so as to improve the design and construction of the piles with variable sections.
