摘　　要：随着海洋、海岸工程日益趋于复杂化,无论是在工程施工还是在设施运营过程中都存在流体-结构物-泥沙相互作用的过程。近年来,计算机技术的飞速发展,为复杂因素影响下的流场及泥沙输移过程的精细化模拟研究提供了必要的技术支撑。本文从计算流体力学的角度出发,总结归纳了目前在海洋、海岸工程中广泛应用的水动力模型和泥沙输移模型。通过梳理各类模型中的湍流模拟方法和泥沙输移模拟方法的特点和适用范围,阐明了现有模型存在的问题及技术挑战,并且从模拟精度及求解效率等方面对流场水动力及泥沙输移过程的数值模型的未来发展趋势做出了合理展望。With the increasing complexity of marine and coastal engineering, fluid-structure-sediment interactions widely exist in engineering construction or facility operation. In recent years, the rapid development of computer technology has provided the necessary technical support for high-precision simulation studies of flow fields and sediment transport processes under the influence of complex factors. This paper summarises the hydrodynamic and sediment transport models that are widely used in ocean and coastal engineering from the perspective of computational fluid dynamics. By reviewing the characteristics and applicability of turbulence and sediment transport simulation methods in various models, the problems and technical challenges of existing models are clarified, while a reasonable outlook on the future development trend of numerical modeling of hydrodynamic and sediment transport processes is made in terms of simulation accuracy and solution efficiency.
