摘　　要：基于室内膨胀土测试试验,对邯郸膨胀土的击实土样的胀缩特性进行了研究。分析了膨胀力与初始含水量、初始干密度及膨胀率与压力、初始含水量及初始干密度的定量关系,并根据膨胀土胀缩变形的物理机制对各因素对膨胀土的影响机制进行了分析。The paper studies the expansive characteristics of expansive soil sample in Handan area based on indoor testing experiment of expansive soil, analyses the quantitative relationship between the expansive force andthe initial moisture content the initial dry density, the expansion ratio and the pressure, the initial moisturecontent, the initial dry density,, analyses the affect mechanism every factor to expansive soil on basis of physicmechanism of expansive soil swell-shrink.
