| 摘 要： | 在岩土破损力学理论的框架内，将结构性黏土看作由不同渗透性能的结构块和结构带组成的二元介质材料，建立了结构性黏土的二元介质渗流模型。进行了一维固结计算，结果说明该模型能与现有二元介质应力应变关系配套进行变形和渗流耦合分析，并能较好地描述结构性黏土的固结过程。

| Abstract: | A new binary medium seepage model is formulated under the theoretical framework of breakage mechanics for geomaterials. In this model, the structured clays are conceptualized as binary medium composed of structured lumps and structured bands with different seepage performances. The model is applied to analyze a 1-D consolidation case. The calculated results show that this new model can easily cooperate with existing binary medium stress-strain relationship for simulating the displacement-seepage coupled consolidation problem and preferably describe the consolidation process of structured clays. |
