| 摘 要： | 以泥沙为主线,结合几场典型洪水,对黄河河潼区间泥沙与洪水的复杂响应进行了分析.结果表明,暴雨分布不同会使河道冲淤变化产生显著差异,暴雨分布于细沙区对下游河床的影响较快."揭河底"、沙坎、异重流等使洪水出现特殊现象."揭河底"会明显降低河道的削峰能力;沙坎会拦蓄部分洪水然后被冲开,使洪水反常增大;异重流及洪水中夹杂的煤块会增加洪水的复杂性.

| Abstract: | This study aims at analyzing the complex responses between sediment movement and flood based on a series of field investigations in Hekou)Tong guan section of the Yellow River.Results show that the channel adjustments such as sediment deposition and erosion vary with the difference of storm distribution pattern./Bed-exposed erosion,sand bar,and density flow are the causes for the abnormal phenomena of floods./Bed-exposed erosion may cut down the ability of flood peak reduction;and sand bar may impound a part of flood and then be broken.As a result,they may cause flood increasing abnormally.Density flow and coalmay make floods more complex. |
