| 摘 要： | 以海口灵山红粘土为研究对象，通过对红粘土进行σ3定值CU与CD试验，利用获得的试验数据进行传统Duncun-Chang模型及改进Duncun-Chang模型参数的标定，并分别对两模型进行实测值与预测值的对比，结果证明，改进Duncun-Chang模型能更好地反映海口灵山红粘土的应力应变关系。

| Abstract: | Taking Haikou Lingshan red clay for the subject,through CU and CD test of fixed value,the parameters of traditional Duncun-Chang model and improved Duncun-Chang model are separately calibrated using the obtained test data,and the measured value and predicted value from these two models are compared.The results show that improved Duncun-Chang model can better reflect the stress-strain relation of Haikou Lingshan red clay. |

| Keywords: | red clay improved Duncun-Chang model Duncun-Chang model stress-strain relation |
