摘　　要：黄土占我国国土面积的6%以上,其中湿陷性黄土占比达到60%左右,山西地区有广泛分布的湿陷性黄土。湿陷性黄土特殊的力学特性主要表现在结构性、欠压密性和湿陷性。正确评价黄土的湿陷性和预测工程运营期间土体饱和度变化所引起的附加变形,对于科学选择技术先进、施工便捷、经济合理的地基处理方法具有重要意义。论文简单介绍了几种近年来出现的低碳环保的地基处理新技术,为湿陷性黄土地基处理提供新思路。Loess accounts for more than 6%of Chinese territory area,of which the collapsible loess occupies about 60%.The collapsible loess is widely distributed in Shanxi Province.The collapsible loess has special mechanical properties such as structural,under-consolidation and collapsibility,and how to correctly evaluate the loess collapsibility and predict the additional deformation caused by the soil saturation change during the engineering operation are of great significance to scientifically select the foundation treatment technology which has advanced technique,convenient construction and reasonable economy.This paper briefly introduces several new low-carbon and environment-protective technologies of foundation treatment in recent years,which provides new idea for treating the collapsible loess foundation.
