Dynamic behavior of pile-supported wharves by slope failure during earthquake via centrifuge tests

Abstract The effects of earthquakes on pile-supported wharves include damage to piles by inertial forces acting on the superstructure, and damage caused by horizontal displacement of retaining walls. Piles can also be damaged through kinematic forces generated by slope failure. Such forces are signi...
