摘　　要：选用水槽和港池物理模型方法以及已有的一些物理模型试验成果,结合SWASH模型,对孤立波在海堤斜坡上的爬高和越浪进行验证,确定合适的计算参数;计算和分析几种不同内坡形式的海堤堤顶决口,确定合适的海堤内坡边界条件。研究分析表明,验证后的SWASH模型可以用来进行海侧来波和陆域越堤波浪的联合计算,为决口海堤洪水波传播模拟和分析奠定了基础。Using the physical model method of the sink and the harbor basin and some existing physical model test results, combined with the SWASH model, the climb and overshoot of the solitary wave on the slope of the seawall were verified, and determine the appropriate calculation parameters were determined;through calculating and analyzing several different types of seawall embankment breaks, the appropriate boundary conditions of the seawall were finalized. The research shows that the verified SWASH model can be used to jointly calculate the waves on the sea side and the waves on the land, and lays the foundation for the simulation and analysis of the flood wave propagation of the seawall.
