石灰桩加固软土地基减小基坑变形技术的理论研究

Theoretical Study on Deformation Reduction of Foundation Pit in Soft Soil Reinforced by Lime Pile

用石灰桩处理基坑潜在危险滑移面上的软土,改良土性,提高软土的抗剪强度和自稳能力,达到减小基坑变形的目标,该技术可作为基坑被动支护的一种辅助手段。

To prevent potential landslide of the deep foundation pit in soft soil, lime piles are used to improve shear strength and self-stability of soft soil to finally reduce the defurmation of foundation pit. The technique introduced can be used as a supplementary means for the passive support of foundation pit.
