| Abstract: | The constitutive model of interface with thickness and
elastic-plastic constitutive model have been employed in order to consider the behavior of
interface element and the plasticity of soils. The research has been made on how the pile
geometry, mechanical behavior of pile, soil mechanical behavior and interface behavior
have influence on the pile settlement by 2D-FEM. Subsequently, several conclusions have
been drawn. |
