| 摘 要： | 针对来自西安市某工程基坑的原状黄土试样进行侧限条件下的增湿变形试验，基于孔隙比、干密度、湿陷系数、净竖向应力等关键指标来分析原状黄土的增湿变形特性。经实验研究发现，侧限条件下的原状黄土净竖向应力达到400 kPa的情况下，湿陷系数达到最高水平。

| Abstract: | A sample of undisturbed loess from an engineering foundation pit in Xi′an was subjected to a humidification deformation test under confined conditions，and the humidification deformation of undisturbed loess was analyzed based on key indicators such as void ratio，dry density，collapsibility coefficient，and net vertical stress.Experimental studies had found that when the net vertical stress of the undisturbed loess under confined conditions reached 400 kPa，the collapsibility coefficient reached the highest level. |
