| 摘 要： | 通过对两种典型地基土，即深黄色粉质粘土与浅紫色粉质粘土进行室内单剪蠕变试验研究，发现当应力水平大于屈服极限时，两者均具有明显的非线性蠕变特性；并对两种粘性土进行非线性流变特性分析，在此基础之上对两种粘性土建立了统一的本构模型。

| Abstract: | This paper researched the creep characteristics of the deep yellow clay and light purple clay by the indoor singleshear test method. Obvious nonlinear rheological properties were discovered for all of them, when the stress was beyond the yieldlimit .Based on analysing the nonlinear reheological properties of two types of clay, a fundamental uniform constitutive model was established for them. |

| Keywords: | nonlinear constitutive model rheological property creep test |
