【摘要】 随着全球气候变暖,海平面上升,超标准台风暴潮时有发生。高潮位与大浪组合往往导致剧烈的越浪或越堤流,冲刷内坡,对海堤安全造成严重威胁。通过物理模型实验,采用流动显示和高速摄像技术,获得规则波作用下越浪水体的运动过程,给出了越浪水体越顶时水质点的流速特征,为进一步分析越浪水体对堤顶及内坡的作用机理打下基础。更多还原

【Abstract】 Recently,along with the global warming,the sea level has been uplifted than before.M ore and more storm surges,which beyond the expected range of wind speed,could generate high risk for the seawall safety.A physical model experiment was designed to study the effect of regular wave overtopping against the seawall,focusing on velocity field properties of overtopping water.By using the high-speed video camera and flow visualization approach,the velocity characteristics of overtopping flows was obtained and discussed.更多还原
