| 摘 要： | 通过引入扰动状态概念(disturbed state concept，DSC)对黏性土的应力应变关系及其压缩变形进行定量分析研究。选取相应土的重塑状态作为土体材料的完全调整状态，土的初始响应为相对完整状态下的行为。建立一个新的扰动模型，反映土在外力作用下微结构的动态变化过程。并通过黏性土的高压固结试验对模型的合理性进行验证，为工程提供更为准确的力学参数。

| Abstract: | This paper is to quantify the influence of soil structure on the stress-strain relationship and analyse compressive deformation. The reconstituded state is chosen to be the full-adjusted state of cohesive soil materials and the initial reflection is considered as the behavior of relative intact state. A new disturbed model is set up for describing the general movement process of microstructure under loading. And the reasonability of model is verified with one dimensional compression test which offered more accurate mechanic factors for engineering. |
