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。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.

关 键 词：红粘土 改进Duncun-Chang模型 Duncun-Chang模型 应力应变关系
