Numerical Analysis of Interaction of Single Pile and Soil Based on ADINA

The interaction between pile and soil can not be ignored in the seismic analysis of long-span bridges. Earthquake action in the form of lateral load apply on the pile through the soil, the analysis of pile under lateral load is very important in aseismatic analysis of bridge. Analysis of the horizontal load pile-soil interaction by using finite element analysis software ADINA, establishing the three-dimensional contact model of pile-soil interaction and the analysis model by using p-y curve model of soil-pile interaction respectively. Comparing the displacement of the top of pile with the actual measurements to verify the numerical method is right. It shows that the feasibility of using ADINA for pile-soil interaction analysis.
