航道通过能力影响因素的分析

以往基于船舶流的航道通过能力计算模型均是在理想条件下提出的,它们只考虑了航道上船舶流的交通特性,其计算结果较实际流量偏大。文中在以往研究成果的基础上,从船舶通航环境的角度,分析了通航环境对船舶行为的影响,并选取相应的修正系数对模型进行修正。修正后的计算模型更能准确地反映航道上的船舶通过能力。

Analysis of the Factors Affecting Traffic Capacity of Navigation Channel

The original mathematic models of navigation channel based on the traffic flow were established under the perfect conditions.The computed results are larger than actual traffic flow because only transportation characteristic of vessel traffic flow is considered in the mathematic model.The paper analyzed the main influencing factors and selected the corresponding modified coefficients which were used to modify the mathematic model in terms of navigation circumstances.The modified mathematical model can exactly describe the traffic capacity of navigation channel.
