两相体模型在评价发泡颗粒轻质土应力-应变特性中的应用

Application of double-phase model to evaluate stress-strain of foamed beads light soil

摘要: 发泡颗粒轻质土是由基材及轻质填充料两种性质不同的材料构成的两相体材料。利用两相体模型建立发泡颗粒轻质土的应力–应变关系,对不同配比轻质土的应力–应变特性进行评价,并利用试验结果对模型的合理性进行验证,为轻质土的工程应用提供必要的理论依据。

Abstract: The foamed beads light soil consisted of base and light filling materials.A double-phase model was established to evaluate the stress-strain properties of foamed beads light soil.At the same time,the laboratory tests results were used to examine the rationality of double-phase model.The results would be helpful for the application of foamed beads light soil in future.
