摘要

Abstract

In the context of global climate change

the impact of group-occurring ocean dynamic disasters on China's offshore areas is becoming more and more intense. The study of the effect of existing ocean dynamic disasters on offshore hazard-bearing bodies mostly focuses on the effect of single disaster-causing factors

and it is still insufficient to study storm surge and dynamic wave coupling & reinforcement effects as well as the process of the dynamic response of such hazard-bearing bodies as seawalls. This study firstly realized the synchronous process of water level and wave through continuous tide generation and wave generation by the wave maker and tide generating device

so as to realize the dynamic coupling simulation of storm surge and wave in the laboratory. Then the physical model test of the typical seawall section was carried out under the dynamic coupling of storm surge and wave as well as at a conventional fixed water level respectively. In the process of test wave overtopping discharge and the damage process of the levee crown and backwall of seawalls were observed and compared

and their damage mechanism was also studied.
