Abstract:

In this thesis, finite element method (FEM)-based numerical analyses are performed to investigate the dynamic behaviour of soil arching. This work begins with the identification of key parameters of pile-supported embankments and their optimum values. Subsequently, the accuracy of the existing analytical methods is improved by incorporating a realistic approximation of vertical stress on the soil arching crown. Finally, mobilisation of soil arching under earthquake and moving train-induced dynamic loading is investigated. The application of a geosynthetic layer is also investigated. The findings of this thesis enhance the current knowledge of the dynamic behaviour of soil arching under the moving train load and earthquake. Also, presented analytical methods can be used for accurate evaluation of vertical stress on the soil arching crown.
