浅析小流量山区河流航道尺度的论证方法

Analysis of channel dimension about mountain river with low discharge

航道整治尺度的确定是航道整治工程可行性论证的重要内容之一,针对山区小流量河流,提出了水力计算法、滩情分析法、类比法,来确定合理的航道尺度。并以赤水河航道整治工程为实例进行了计算和综合分析,工程实践表明提出的计算方法是有效的。

One of the important content in feasibility study of channel regulation is the determination of the channel dimension. As to the low discharge mountain river, the methods of the hydraulic calculation, analysis of the beach condition and analogy are proposed to determine the appropriate channel dimension. And the methods are used to calculate and analysis Chishui River channel regulation project. The practical construction shows that the proposed calculation method is effectiveness.
