在航道的规划和设计中,要通过多种途径测算航道的通过能力,其中包括利用公式进行估算。目前国内外已经总结出了一些经验公式,这类公式的共同特点是有一系列待定系数需根据实际情况和资料加以分析确定。本文以汉江襄樊以下的航道开发为实例,对西德和我国长江两个经验公式中的各项系数的采用及其计算成果,进行讨论,以供有关方面参考。
In the planning and design of waterways, the capacity of waterways to be measured through various means, including the use of formulas. At present, some empirical formulas have been summed up at home and abroad. The common characteristic of these formulas is that a series of pending coefficients need to be analyzed and confirmed according to the actual situation and data. This paper takes the channel development below Xiangfan in the Hanjiang River as an example to discuss the adoption of the coefficients in the two empirical formulas of the West Germany and the Yangtze River in our country and the calculation results for the reference of relevant parties.
