| Abstract: | The finite element model for a typical pile with enlarged base is established,in which the elastic-plastic material model is used for soil and the contact elements are defined on the interface between the pile and the soil.The analysis on the characteristic of uplift load transmitting and the pullout resistance capacity of the pile with enlarged base is performed.The distribution of the friction on the side of pile,the development of the plastic region of soil and the effect of the pile length and the soil ... |
