摘要: 开展溃坝水流计算对溃坝过程进行模拟,预测溃口发展及溃坝洪水过程线,对于大坝失事后果的评估,防洪减灾以及保护人民生命财产安全等具有重要意义。研究了常见溃坝水流计算方法,例如溃口平均宽度、坝址最大流量、坝址流量过程线等。最后利用溃坝计算方法对某尾矿库溃坝砂流进行了预测。

Abstract: Calculation of dam-break water flow is of great significance to the dam-break simulation, break evolution prediction, flood hydrograph prediction, damage assessment, disaster control and people's life and property protection.The calculation methods for common dam-break water flow are studied, such as the average width of dam-break, the maximum flow at tailing dam and the flow graph at tailing dam.Finally, the method is used to forecast the tailing flow in case of a dam break of a tailing reservoir.
