The key factors affecting settlement in ground fillings

In this paper,a model of roadbed and ground is established by using the elastic-plastic finite element method and the method of stratification incremental loading is also used.By selecting the elasticity coefficient,the cohesive force,the angle of internal friction as parameters,the real process of stress and the distortion and subsidence of roadbed and the foundation soil in various construction stages is simulated.The results show that distortion and subsidence of ground under the effect of th...
