A Study of Wave-induced Dynamic Stresses in Sandy Seabed in front of Vertical Breakwater

摘要

In this study, a series of hydraulic model tests with movable seabed was carried out to investigate the dynamic interactions between water waves and seabed soil in front of vertical breakwater. The results show that the typhoon wave nonlinearity, movable seabed induced wave damping, and wave period can affect the dynamic stresses in seabed soil. The seabed soil at standing wave anti-node is subjected to uniform stresses and has similar stress path as in fluid in shallow depth. The stress path at deeper depth can be treated as soil behavior in undrained condition.
