【摘要】 用水动力学方法研究洪流演进问题是水文学研究的一个新途径。本文在前人研究的基础上,论证了马斯京根演算模型具有坦化变形的特征,且数值计算是稳定的和收敛的;通过对马斯京根模型的水动力学研究,对几种模型作了比较,解释了Fr=0的物理意义,并列出了几种常见断面形状和摩阻关系的波速及马斯京根参数公式表,可供实用参考。文末还对柘溪水库下游的洪流演进作了计算。更多还原

【Abstract】 Based on predecessors’ studies, it is proved that the Muskingum model has attenuation and deformation properties, and numerical computation is stable and convergent. By studying the Muskingum model in hydrodynamics, a comparison between several models is made, and physical significance of Fr=0 is explained. For several common cross-sections and friction laws, the celerities and tie Muskingum parameters are listed. This can be used for reference in practice. The flood routing in the downstream of Zhexi Water Power Station is calculated in the end of the paper.更多还原
