| 本文通过实测资料分析和泥沙数学模型计算的方法，就如何塑造并维持黄河下游中水河槽进行了系统的研究，分析了在未来可能的水沙条件下黄河下游中水河槽的规模，计算了小浪底水库不同出库水沙条件对塑造黄河下游中水河槽的作用，认为在目前的水沙条件下塑造和维持平滩流量约4000m3/s的中水河槽是可能和现实的，并进一步分析了影响中水河槽塑造和维持的主要因素，提出了塑造和维持黄河下游中水河槽的措施，试图为黄河下游防洪治理和维持黄河健康生命提供技术支持。图4表2参8 |
| 英文摘要: |
| A system study on how to reform and maintain the river channel for medium flood in the lower Yellow River is carried out based on the field data analysis and numerical simulation, aiming at the target of elevating the flood control capacity of the river and maintaining the Yellow River as a healthy river. The probable scale of medium flood river channel under the likely flow-sediment conditions in the near future is calculated and the effect of different operation modes of the Xiaolangdi Reservoir is analyzed. The study results show that it is possible and realistic to reform and maintain a river channel in lower Yellow River for safely transport a bank full discharge of 4 000m3/s. Furthermore, the main factors influencing the reform and maintenance are studied and corresponding measures are suggested. |
