| 摘 要： | 论述了轻质土试样的制备方法，对轻质土密度、无侧限抗压强度与材料组成之间的关系进行的研究表明：密度主要受到EPS颗粒添加量的影响；无侧限抗压强度主要受到水泥添加量、EPS颗粒添加量的影响。在此基础上给出了适合于工程应用的轻质土的配方公式。

| Abstract: | The method to prepare lightweight soil specimens is discussed. The results from the studies on the relationship among density, unconfined compressive strength and compositions of lightweight soil specimens have shown that the density is mainly influenced by the addition amount of EPS grains but the unconfined compressive strength is mainly influenced by the addition amount of both cement and EPS grains. On the above basis, the mixture proportion equations applicable to engineering uses are given. |

| Keywords: | lightweight treated soil expanded polystyrene(EPS) density unconfined compression strength recipes formula |
