本文提出了一个计算循环荷载作用下砂土中永久应变和应力的数值模型。该模型与排水静、动三轴试验结果吻合较好。该模型可以预测在各种边界条件下，排水或不排水循环荷载所产生的永久应力和应变。将模型预测值与循环固结试验和循环不排水三轴试验结果进行了比较。预测响应和测量响应之间存在良好的相关性。
This paper presents a numerical model for calculating permanent strains and stresses in sand caused by cyclic loading. The model is fitted to the results of drained static and cyclic triaxial tests. The model can predict permanent stresses and strains resulting from drained or undrained cyclic loading under various boundary conditions. Predictions of the model are compared with experimental results from cyclic oedometer tests and cyclic undrained triaxial tests. Good correlation exists between the predicted and measured response.
