| 摘 要： | 针对混合塑料发泡颗粒轻质土的特性,利用两相体模型提出了对其强度及变形等工程性质进行评价的方法;并运用该方法,在考虑构成轻质土两种不同材料性质的基础上,对轻质土的强度与变形特性进行了分析。结果表明:该方法可以比较合理地对塑料发泡颗粒轻质土的应力-应变特征及强度特性进行评价;轻质土强度随轻质填充料体积分数的增大而减小,随龄期的增长而提高。

| Abstract: | Based on properties of foamed beads light soil,using double-phase model,the evaluation approach on the strength and deformation properties of foamed beads light soil was proposed.The double-phase model is effective to analyze the strength and deformation properties of foamed beads light soil considering two kinds of different materials properties of light soil.The results show that the method can be applied to strength behaviors and stress-strain characteristics of plastic foamed beads light soil.Light soil strength decreases with increase of light fillings volume percentage and increases with increase of age. |
