| 摘 要： | 当含水量发生变化膨胀土产生膨胀变形时，在侧限状态下，膨胀土表现出很大的膨胀力。文中采用膨胀试验研究了陕南地区膨胀土的初始物理状态(即干密度、含水量和孔隙比)对膨胀力的影响。并建立了初始物理状态与膨胀力的线性关系，提出了陕南地区膨胀土膨胀力的计算式。

| Abstract: | When expansive soil swells due to changes of water content,under unconfined state,expansive soil shows larger expansibility.This paper studies the initial physical state（i.e.dry density,water content and void ratio） of expansive soil in Southern Shanxi Region based on expansion test.It establishes the linear relation between initial physical state and expansibility and puts forward the formula of expansive soil expansibility in Southern Shanxi Region. |
