摘　　要：针对目前尾矿库溃坝研究大多没有考虑真实地形地貌的影响,对现状地形简化较多以致于对溃坝灾害的评价与真实情况有较大偏差的问题,本文以江西某尾矿库为例,借助Civil3D软件对坝体及其下游1 000 m范围的实体地形及村庄分布进行三维建模,并利用FLOW3D流体动力学分析软件对溃坝砂流演进过程进行了模拟分析。重点分析了溃坝后尾砂流影响区域的洪水流速场、溃坝洪峰的演进过程以及溃坝洪水的淹没范围,对溃坝洪水是否淹没或冲击敏感目标进行了评估。The effect of the real terrain and topography has not been considered in the current researches of tailings dam break, the more simplification of the current terrain results in a large deviation between evaluation of dam break disaster and the real situation. Taking a certain tailings dam of Jiangxi as an example, with the help of Civil3D software, 3D modeling is carried out for the physical terrain and village distribution of dam body and its downstream 1 000 m range, and the evolution process of dam break sand flow is simulated and analyzed by using FLOW3D fluid dynamics analysis software. This paper focuses on the analysis of the flood velocity field, the evolution process of the dam break flood peak and the submerged area after the dam break, and makes an assessment bf whether the dam-break flood submerged or the sensitive target impacted.
