The 3D reproduction of dam-break floods plays a key role in emergency management and disaster information dissemination. However, existing systems for the simulation of floods have some deficiencies. First, the input data parameters are complex. Second, the simulation process is cumbersome and time consuming, and it lacks a complete workflow. In this paper, we develop a platform for the rapid 3D reproduction of dam-break floods. Key technologies, such as numerical models of dam-break floods based on cellular automata (CA), 3D reproduction constrained by post-disaster information, and dynamic augmented representation, are discussed in detail. Then, two typical dam-break flood cases are selected for experimental analysis. The experimental results show that the system can support the rapid 3D reproduction of dam-break floods constrained by post-disaster information. Compared with that of other simulation systems, the reproduction time is reduced to less than 1 h, and this system supports rapid reproduction at different times and positions.

溃坝洪水的3D复制在应急管理和灾难信息传播中起着关键作用。但是，现有的洪水模拟系统存在一些缺陷。首先，输入数据参数很复杂。其次，仿真过程繁琐且耗时，并且缺乏完整的工作流程。在本文中，我们开发了一个用于溃坝洪水的快速3D复制的平台。详细讨论了关键技术，例如基于元胞自动机（CA）的溃坝洪水数值模型，受灾后信息约束的3D复制以及动态增强表示。然后，选择了两个典型的溃坝洪水案例进行实验分析。实验结果表明，该系统可以支持受灾后信息约束的溃坝洪水的快速3D复制。与其他模拟系统相比，该系统的再现时​​间减少到了不到1小时，并且该系统支持在不同时间和位置进行快速再现。
