| 中文摘要: |
| 针对封堵溃口问题，根据流体力学理论，建立了重物落水后运动过程的数学模型，利用小型试验获取相关数据的方法进行研究，用该模型对实验的工况进行了计算，并对模型和实验进行了分析和评价.通过实例，验证了该模型较好地模拟了大坝溃决后的重物落水后的运动过程，模型结果可以为溃坝洪水风险提供科学依据. |
| 英文摘要: |
| In this paper,a mathematical model for the dam failure with the weights into water was established by the fluid dynamics theory.The model was applied to the small-scale test by which we obtained relevant data.The model simulated the movement process of weights into water,according to comparison between the calculated value and measured data.This model can provide a scientific foundation for the risk of dam break flood. |
