| 摘 要： | 根据室内三轴流变试验的结果，研究了北京地区粉质粘土的流变特性。结果表明，该类软土具有较明显的变形时效性及其在不同应力水平下的蠕变特性。通过分析蠕变曲线的规律，选择了广义开尔文五单元理论模型和时间硬化经验蠕变公式来描述软土的流变特性，并达到了良好的精度，建立了适合北京地区典型软土的流变理论模型和经验模型。

| Abstract: | Based on the data of rheological test,the rheological properties of soft soils in Beijing district are studied.The obvious time characteristics of the soft soils as well as its rheological properties under different stress levels are demonstrated.Generalized Kelvin model with five-components and time hardening experiential creep model are chosen to describe the creep characteristics according to the analyses of the laws of the creep curves,better precision is proved on the two models and rheological model o... |
