湿陷性黄土在我国主要分布在山西、陕西、甘肃的大部分地区,是一种非饱和的欠压密土,具有大孔和垂直节理,在天然湿度下,其压缩性较低,强度较高。但遇水浸湿时,土的强度显著降低,在附加压力与土的自重压力下引起的湿陷变形,是一种下沉量大、下沉速度快的失稳性变形,对建筑物危害性大。本文从湿陷性黄土发生的原因、评定以及处理措施等方面进行本工程湿陷性黄土处理的探讨与研究。

Collapsibility loess is a kind of unsaturated soil and incomplete consolidation soil with macroporous and vertical joints ,existing in the most area of the provinces of Shanxi Shanxi Gansu .In the natural humidity ,the compressibility of collapsibility loess is lower ,but its strength is higher .With soaking of water, strength of the collapsibility loess becomes significantly lower. Collapse deformation caused by the additional pressure and the soil weight pressure ,is a kind of instability deformation with large and fast sinking ,which also brings heavy danger to Buildings .In this paper, based on the principle ,evaluation and handling of the collapsibility loess, the author discussed and researched the treatments of the collapsibility loess for our project.
