摘要: 严格分析了路基土在三轴试验条件下回弹模量的应力依赖性模型理论, 对现行模型所存在 的问题进行了更正, 提出了路基土乃至整个土工材料回弹模量的应力依赖性模型理论. 通过重 复三轴试验及模型理论建立了路基土回弹模量的应力依赖性模型, 该模型可供柔性路面结构非 线性分析使用.

关键词: 路基土, 非线性, 回弹模量, 应力依赖性模型, 重复三轴试验

Abstract: It is evident that the responses of subgrade soil are non-linear and hence, with a large number of experiments and theoretical studies, this paper analyses the stress-dependency model of the resilient moduli and modifies the foreign widely-used model in existing deficiency and theorial inaccuracy. Based on the stress-dependency model, using the repeated load triaxial test, the paper analyses the stress-dependency of the subgrade soil resilient moduli for the first time in China.

Key words: subgrade soil, non-linear, resilient moduli, stress-dependency model, repeated load triaxial test
