We studied the relationship of humidifying deformation and water immersion content from the unsaturated to the saturated states and analyzed the factors influencing humidifying deformation in water immersion of compacted loess. Humidification axial strain was mainly affected by deviatoric stress, and the influence was significant. We studied the deformation characteristics of compacted loess under water immersion using a CT-triaxial wetting collapsibility test system. Our test results demonstrate that under certain environmental conditions, changes in water content may cause wetting deformation, which exhibits a large impact on the structural characteristics of soil samples. A relationship between the initial state of water content and the water content state under constant stress was established. The results demonstrated that the expression characteristics of humidification level parameters were consistent with the evolution characteristics of structural parameters. This provides a basis for the establishment of a soil strain damage model and quantitative structural indexes.

研究了从不饱和状态到饱和状态的加湿变形与浸水量的关系，并分析了压实黄土浸水加湿变形的影响因素。加湿轴向应变主要受偏应力的影响，影响很大。我们使用CT三轴润湿湿陷试验系统研究了压实黄土在水浸下的变形特性。我们的测试结果表明，在某些环境条件下，水分含量的变化可能会导致润湿变形，这对土壤样品的结构特征影响很大。建立了水的初始状态与恒应力下的水状态之间的关系。结果表明，加湿水平参数的表达特征与结构参数的演化特征一致。这为建立土壤应变破坏模型和定量结构指标提供了基础。
