摘要
以粉质软粘土为研究对象进行室内蠕变实验,对比分析土体结构性变化对流变特性的影响。提出土体结构性影响系数的概念。根据试验数据确定应力效果参数与应力水平的关系式,进而建立了软土的结构性宏观流变力学模型,描述了软土结构改变后的流变规律。
The paper puts soft clay as study object,makes rheological test and deduces the impact of structural change of clay on macro rheological characteristic.The author summarized the content of structural influence coefficient.According to the experimental data,the author established the relation of stress-effect parameter and stress.Finally,a structural rheological model of soft soils was set up,which can describe the rheological law of soft clay after structure change.
