| 摘 要： | 本文通过资料分析，在前人已有工作基础上，提出了通过统一的二维模型替代以往一维和二维模型嵌套方法的理论基础，探讨了基于此新的概念模式进行数值计算的网格剖分。利用作者以往的洪水冲刷试验研究成果模拟土石坝溃坝发展过程中的逐渐溃模式，探讨了土石坝逐渐溃的溃坝模式数值描述方法，溃坝洪水过程的数值模拟等。文中还介绍了一个实例计算。

| Abstract: | A new approach to mesh generation is proposed to integrate the conventional 1-D and 2-D calculation method of dam break wave propagation into a single unified 2-D model under the same controlling equation. By this approach the problems of connecting the 1-D model with 2-D model can be avoided. On this basis a model for describing the dam break wave with gradually breaking process is established. The application of this model is used to predict the flooding in the downstream of a reservoir due to dam break. |
