| 摘 要： | 通过时Q2和Q3黄土的单轴压缩和常规三轴试验研究，对两种黄土单轴压缩曲线和CU剪切的应力应变曲线特征进行分析比较，探讨了两种黄土应力应变本构模型。研究表明：强软化型Q2黄土应力应变关系，可采用强软化型模型进行描述，并对其模型参数进行了分析；弱软化-硬化型Q3黄土应力应变关系可用两参数的指数模型描述，也可用强软化性模型描述。 |
| 关 键 词： | Q2和Q3黄土 力学特性 应力-应变本构模型 |

| Abstract: | On the basis of the uniaxial compressive test and routine triaxial test results of Q_2 and Q_3 loess,the features of strain-stress curves of Q_2 and Q_3 loess are compared.The stress-strain constitutive models of two types of loess are discussed,the results show that the strong softening strain-stress constitutive relationship of Q_2 loess can be described by strong softening model,and the model parameters are analysed,strain-stress constitutive relationship Q_3 loess with weak softening-harden can be described both by strong softening model and exponential model with two parameters. |
| Keywords: | Q_2 and Q_3 loess mechanical features strain-stress constitutive model |
