Seismic dynamic response analysis of permeable breakwater on piled foundation considering pile-soil interaction

In order to discuss the seismic response of pile foundation permeable breakwater structure under different working conditions, the dynamic implicit module in finite element software ABAQUS is used to analyze the seismic dynamic response of pile foundation permeable breakwater. Considering the nonlinear characteristics of pile-soil interaction the breakwater is simulated under different seismic intensity conditions. The acceleration, bending moment of pile foundation are analyzed by time-history analysis method. The influence of pile diameter on the whole structure is compared. The results show that the stronger the earthquake is, the more obvious the overall dynamic response of the structure is. The bending moment of pile body decreases first and then increases. The wider the diameter of pile foundation, the greater the stiffness of the whole structure, resulting in an increase in the seismic force received by the structure. Compared with the static load, the influence of earthquake on the permeable pile breakwater can not be ignored. (paper)
