3D Numerical Research on Dynamic Response of Pile Foundation in Water Plant Structure in Fill Site
Pile foundation is a widely used foundation in fill site.Based on a water plant construction project in southwest China,a 3D calculation model is established by ABAQUS.The acceleration,bending moment and shear force response of the pile are analyzed,and the dynamic response law of foundation-pile foundation-structure under ground motion is discussed.The results show that the pile acceleration increases with the increase of the pile height,and the amplification effect at the top of the pile decreases slightly.The dynamic response of the pile group foundation varies at different positions,and the bending moment and shear force of the corner pile closest to the filling area are the largest.
