摘　　要：溃坝是一种伴随有巨大破坏力的灾害性的水流现象。溃坝常会造成坝体下游河床的水流急剧增长甚至漫槽形成立波向下游急速推进,对大坝下游造成强烈破坏,从而引起巨大的经济损失甚至人员伤亡。因此,针对瞬间全溃模型,利用Hydro Info软件三维自由水面模型,采用分层Euler-Lagrangian计算模式建立平面上非结构化网格及垂向分层动网格,并采用VC方式的非结构化有限体积方法离散浅水方程求解,模拟溃坝水流的流动过程。结果表明,该软件能够准确模拟溃坝水流的传播过程。Dam break is a disastrous water phenomenon with great destructive power. dam break often causes rapid growth of the water flow and rapid advance of the vertical waves in the downstream of the river,causing serious damages,huge economic losses and even casualties to the downstream area of the dam. Therefore,dam break is always one of the special concerns in the design and management of water conservancy projects. In this research an instantaneous dam break flow was simulated by Hydro Info,which uses the hierarchical Euler-Lagrangian calculation model to build the horizontal unstructured mesh and vertical layered dynamic grid,and uses the VC（ Vertex-Centered） unstructured finite volume method to solve the discrete shallow water equations. The results indicate that Hydro Info can accurately simulate the propagation process of the water flow in dam break.
