摘要
通过对西北地区原生与重塑膨润土的湿化试验,研究了初始含水量、初始干密度与荷载水平对湿化变形的影响。研究表明,当初始干密度给定时,湿化变形增量随初始含水量增加而减小;当初始含水量给定时,湿化变形增量随初始干密度增加而增大。重塑膨润土也同样有此规律,但重塑膨润土的湿化变形比原生膨润土为大。
Trough the humidification deformation test of original expansive soil and remodeling expansive soil of northwest china,the influence of three kinds of factors that are the initial water content,the initial dry density and load level on two kinds of soil is researched on.The results show that：when the initial dry density is certain,the humidification deformation decreases with the increase of the initial water content;When the initial water content is certain,the humidification deformation increases with the increase of the initial dry density.The humidification deformation law of remodeling expansive soil and original expansive soil is same,but humidification deformation of remodeling expansive soil is larger than the original expansive soil.
