| 摘 要： | 本文根据黄河河曲段六个封冻期的原型观测资料,对该冰塞河段冰期的河床演变及水内冰花在冰塞下的堆积——冰塞演变,进行了分析研究。总结出冰塞河段的河床演变特点与冰塞演变的相互关系,得出了河床冲淤及水内冰堆积计算的经验关系式及河床冲淤平衡的临界水力参数。文中还对有关冰期输沙的若干问题进行了讨论。

| Abstract: | Analyses and studies have been made on scouring and deposition in riverbed and accu-mulation of frazil ice under ice jam in Hequ Reach of the Huang He (Yellow River) during ice periods, based on prototype observation data of during periods. The relationship between the particular features of scouring and deposition of riverbed and evolution of ice jam in He-qu Reach has been obtained. Empirical formula for computation of scouring and deposition in riverbed and values of hydraulic paramters for equilibrium of riverbed with respect to scou-ring and deposition have been preseuted. Problems related to sediment delivery in ice periods have also been discussed in this paper. |
