| 摘 要： | 发泡颗粒轻质土是一种比较新颖的土工材料，具有质量轻、强度高等特点。在道路、桥梁、建筑等领域有着广泛的应用前景。为了探讨轻质土的工程特性，利用室内试验及理论分析的方法对发泡颗粒轻质土的强度、变形特性以及影响因素进行了分析。根据分析探讨的结果，利用轻质土的构成特征所建立的两相体计算模型可以比较合理、可靠地分析轻质土的应力-应变特性，并在此基础上可方便地应用计算模型分析时间、轻质填充料含有率等因素对轻质土的强度、变形特性的影响，为轻质土的工程应用提供必要的理论依据。

| Abstract: | The foamed beads light soil is a new soil materials with the features of lightweight and high strength; it can be used for road base, bridge and other construction applications widely. In order to evaluate the engineering properties of foamed beads light soil, the strength and deformation properties of foamed beads light soil are analyzed based on laboratory tests and analytical method. Based on the results, the double-phase model is utilized to evaluate the stress-strain properties of foamed beads light soil. By this analytical method, it will be helpful to evaluate the influences of ca.ring time, light filling volume ratio on strength and deformation properties of foamed beads light soil. Thereby, the results will be useful for the application of foamed beads light soil in future. |
