摘要
通过室内膨胀土土样的膨胀试验，研究不同击实膨胀土土样在不同压力作用下膨胀变形与土样初始含水量、干密度的关系，总结膨胀上的膨胀变形规律。同时研究不同土样的膨胀力与初始含水量、干密度之间的相关性。此对研究膨胀土的变形和强度很有必要。
The expansion test of unsaturated expansive soils is performed in laboratory. The relationship of expansive strainwith initial water content and dry density of expansive soils is studied and the laws of expansive strain of unsaturatedexpansive soils are analysed. At the same time. the relationship of the expansive force with initial water content and drydensity of expansive soils is sutdied. This research work is important for the study of the strain and strength of unsaturatedexpansive soils.
