| 摘 要： | 在对成都粘土流变本构模型进行研究的基础上,应用Burgers体模型对成—绵—乐高速铁路成都牛龙路一带地基土建立目标函数。运用分层迭代反演土层的粘-弹性参数,以实测地基沉降为基础,对观测后期沉降进行预测,并与后续观测记录对比,从而验证了Burgers模型可在一定精度下满足沉降预测的要求,为本工程安全运营提供指导,并为同类研究提供了依据。 |

| Abstract: | Based on Chengdu clay rheological constitutive model, this article applied the Burgers model to establish the objective function for foundation soil in the area of Chengdu Niulong Road in Cheng-Mian-Le high-speed railway. By the method of iterative back analysis by layer of visco-elastic parameters, based on measured result, predicting the late settlement, and comparing with the follow-up observations records to verify the Burgers model can meet the accuracy requirements of settlement prediction, so as to provide guidance for the safe operation of the project, and also provide a basis for similar studies. |
| Keywords: | Chengdu clay Burgers model parameter inversion settlement prediction |
