摘 要:对小浪底水库运用之前黄河干流洪峰增值现象的研究进行了回顾,对小浪底水库运用后洪峰增值的洪水场次进行了系统整理,并对近期黄河洪峰增值现象的研究成果进行了综述,指出了已有的河槽形态变化观点、"孤立波"和"水跃"观点、减阻观点、密度差观点、沙坝观点、扰动说等研究成果存在的问题,认为小浪底水库运用前后小浪底—花园口区间洪水洪峰增值机理是相同的,与洪水是否漫滩无关。另外,建议加测足够的野外资料,然后从理论上分析洪峰增值的机理。This paper reviewed the study on the phenomenon of flood peak increase for sediment concentration flood in the Yellow River before 2000,and organized the research results of flood peak increase in recent years. This paper pointed out the existing problems about the viewpoints channel pattern variety,solitary wave,hydraulic jump,drag reduction,density difference,sandbank and disturbance. It is considered that the mechanism of flood peak increase before and after 2000 and flood peak increase had nothing to do with bank overflowing. It was suggested to ob-serve more field data and then to analyze the mechanism theoretically.
