摘要
基于有限元分析软件及高铁路基实际施工图纸,建立了含CFG桩的复合地基计算模型,并采用可蜕化为广义开尔文模型的粘弹性蠕变模型开展了蠕变计算研究,分析了高铁路基在填筑完成后不同时期的蠕变变形分布特征,揭示了路基上不同部位特征点的蠕变变形演变规律。
The calculation model of composite foundation with CFG piles is set up,based on the finite element method and combined with the actual construction drawings of the roadbed. The numerical calculation is carried out by using the creep model. The settlement and deformation of the foundation is clarified in different periods after the completion of filling. And the settlement change law of the characteristic points on different parts of the subgrade is revealed.
