| Abstract: |
| The explicit equations of stress,displacement and excess pore-water pressure are derived by solving Biot’s consolidation equations through Laplace and Hankel transforms.An analysis is developed on semi-infinite viscoelastic body with Kelvin model.The reasonable results show that the present theory is correct and with high accuracy and efficiency.The results show that as the depth increases,the excess pore-water pressure first increases to its maximum and then decreases.The volume strain increases rapidly in the early stages of the load.The speed of the volume stain’s increase slows down with increasing time. |
