摘要
本文在理论分析的基础上,建立了异重流头部运动速度及稳定厚度的计算公式。通过数值求解证明了异重流稳定厚度约为环境水深的0.5倍左右,并对所提出的公式进行了化简。研究结果表明,本文提出的异重流厚度计算表达式与现有的观测结果是一致的,异重流头部运动速度表达式与现有的研究成果也是一致的。
Based on the theoretical analysis, the formula for calculating the gravity current movement speed and stable depth behind the head of a gravity current over a horizontal channel bed surface are established. From the numerical analysis, the assumption that the stable depth is half of the ambient water depth in open channels approximately has been prooved, and the formula are simplified. The investigation shows that the formula presented in this paper have good agreement with measurments and the results of present research.
