摘要
本文就低含沙洪水与高含沙洪水对河床的冲淤模式进行了描述,在对洪水冲刷河床的力学机理进行分析的基础上,初步建立了来水来沙与河床基本相互适应的条件下洪水冲刷深度与来水来沙的关系,并用黄河干支流资料进行了讨论与验证。该公式考虑因素简单,计算方便,同时适用于低含沙与高含沙洪水。
Hyperconcentrated flow is a peculiar phenomenon in the Yellow River and its tributaries. Floods often result in tremendous erosion with a depth up to 10 meters. Such phenomenon is investigated and the scour modes for river cross-sections are described. A formula of scour rate based on the momentum equation is verified by field data.
