摘要

干旱半干旱区路基黄土由于相对湿度低、地下水位深而处于高吸力条件下。了解非饱和压实黄土在大吸力范围内的水力学行为对于解决此类地区的基础设施问题至关重要。本研究采用轴平移技术、蒸汽平衡技术和冷镜露点技术，通过施加或测量吸力来研究黄土的保水行为。此外，还进行了三轴试验，研究了压实黄土在不同净胞压(

Hydromechanical behavior and prediction of unsaturated loess over a wide suction range

Subgrade loess in arid and semi-arid regions subjected to high-suction conditions owing to low relative humidity and deep groundwater levels. Understanding the hydromechanical behavior of unsaturated compacted loess over a wide suction range is critical for resolving infrastructure problems in such areas. In this study, the water retention behavior of loess was investigated by imposing or measuring suction (s) using the axis translation technique, vapor equilibrium technique, and chilled mirror dew point technique. Triaxial tests were also performed to study the mechanical behavior of compacted loess under different net cell pressures (
