| Abstract: | A three-dimensional finite element solid model is set up by using ANSYS.The dynamic interaction between pile-soil under earthquake is calculated.The seismic responses are discussed including acceleration response,displacement response,strain response of pile,deflection of pile,bending moment and shear force of pile,contact pressure on the pile-soil interface.The parameters influenced pile-soil system,such as soil property,rigidity ratio between pile and soil,and so on are discussed. |
