摘要
膨胀土是一种遇水膨胀，失水收缩，易开裂、多坍滑的特种土。对膨胀土用水泥、二灰进行改良，通过室内试验研究，提出了灰土的最优掺灰比。
Expansive soil is a kind of special siol which sweels when it absorbs water and shrinks when it loses water. It is easy to crack and collapse. Cement and flyash were added to the expansive soil. According to the result of laborary experimental research on the improvement of the expansive soil, the optional cement content and flyash content is presented in this paper.
