Study on the Dynamic Response and Anti-Collapse Mechanism of High-Pile Wharfs with Different Water Depths

In recent years, many earthquakes occurred all over the world and caused different degrees of damage to the engineering structures. Therefore, it is increasingly important to ensure the safety and stability of the port structure and to study the seismic performance of the wharf structure. Considering pile-soil interaction, numerical simulations of high-pile wharf were done by using the finite element method, and the displacements, bending moments and shears of the 7m wharf were obtained subjected to different kinds of earthquake waves, such as far-fault and near-fault seismic waves. The plastic characteristics of the wharfs with different water depths(7m, 10m, 12m) were researched subjected to seismic waves with different peak accelerations and advises for the anti-collapse mechanism of the wharfs were provided.
