摘　　要：回顾和总结了国内外基于有限体积法对溃坝水流模拟的研究进展,讨论了使用非结构网格的优劣,并介绍了法向数值通量计算格式的特点、守恒变量重构方法及限制器的应用,探讨了在溃坝模拟中的边界及地形问题,提出了进一步发展的趋势。This paper summarizes the research progress of dam break water flow simulation with finite volume method and discusses the advantages and disadvantages of unstructured grids. And then it introduces the characteristics of the formula for normal numerical calculation flux, reconstruction method of conservation variables and application of limit de- vice. Finally, the boundary and terrain simulation problem for numerical simulation of dam break is explored and the fur- ther development trend is proposed.
