摘 要: 结合Dean、Bodge和Lee提出的海滩平衡剖面模型对后江湾剖面模拟的结果,分析了模型中参数的物理意义,并探讨了模型参数之间的关系。认为模型中的多数参数的物理意义是比较明确的,与实际海滩特征也吻合较好。其中,Dean模型中的m和Bodge模型中的K1代表剖面反射性(上凹曲率);Bodge模型中的B和Lee模型中的K2含有特征波要素意义;Dean模型中的A与Lee模型中的Al泥沙特征有关。为这些模型在海岸工程中的应用提供了方便。但模型中有些参数的物理含义还需进一步研究,参数之间的关系还需要更多验证。 The beach profile of the Houjiang Bay are fit with eqilibrium beach profile(EBP) models advanced by Dean, Bodge and Lee, which are typical EBP model. By analysing the fit results, the physical meanings within the EBP model parameters and the relation between the parameters are discussed. The results show that most parameters have clear physical meanings and can accord with the that of the natural beach well. In which, m (in Dean's model) and K1 (in Bodge's model) represent beach profiles' reflectivity (rate of concave curvature), B (in Bodge's model) and K2(in kee's model) represent characteristic waves, A (in Dean's model) and &(in kee's model) have relevants with sediment characters. These results have good foreground in coastal engineering application. Some parameters' physical meanings and relations need further studies.
