| 摘 要： | 对以砂土为原料土、以水泥为固化材料的EPS颗粒混合轻质土进行了一系列室内试验。结果表明：压实条件和含水率对其密度和强度有很大的影响，存在适宜压实次数和最优含水率；对施工含水率对其应力-应变关系的影响进行了分析，得到在水灰比一定的情况下强度与水泥的添加量的线性关系。

| Abstract: | A series of laboratory tests were carded out to investigate the physico-mechanical properties of EPS beads-mixed lightweight soil which is made of sand and treated with cement. Results show that the compaction and moisture content of the treated soil have significant effects on its density and strength. There exist suitable compaction times and optimum moisture content. The effect of the moisture content during sample preparation on the stress-strain relationship was analyzed and linear relationship was obtained between the strength and cement content with fixed water-cement ratio. |
