水库异重流是一种特殊的水流现象,在多沙河流水库上利用异重流排沙可提高水资源的利用效率。本文对韩其为推导的水库异重流不平衡输沙规律公式进行新的推导,探讨了该公式在浑液面变化条件下的规律,并利用小浪底水库实测资料进行了验证。结果表明,采用公式计算可提高预测精度。
Turbidity current in reservoir is a specific phenomenon in nature, which could be used for sediment flushing to i improve water resource utilization efficiency in reservoirs on sediment-laden rivers. For the conditions of muddy lake surface changing, this paper modifies the formula of turbidity current non-equilibrium sediment transport derived by Han Qiwei. This new formula was verified with the field data surveyed in the Xiaolangdi reservoir and showed an improved accuracy of calculation.
