| 摘 要： | 用室内三轴试验得到了加筋粘土的应力-应变关系，在此基础上建立了基于RBF神经网络的加筋粘土本构模型，利用此模型对加筋土在不同加筋层数情况下的本构模型进行仿真，并将其与试验值进行对比。结果表明，RBF神经网络能够很好地逼近加筋粘土的本构关系且具有较强的泛化能力，可以反映加筋层数和应力路径的影响。

| Abstract: | Indoor,triaxial tests were carried out to obtain the stress-strain relationship of reinforced clay.A RBF neural network constitutive model of reinforced clay was established based on test data.The authors used it to simulate the constitutive model of reinforced soil under different reinforced layers.Compared with the experimental value,the result shows that,the RBF neural network has a good approach to the constitutive relationship of reinforced clay and a strong generalization ability.It can reflect well t... |
