基于可接受间隙理论的交汇段次航道通过能力

Passing Capacity of Minor Chamelay Based on Alterway Intersection Waterway

为研究内河交汇段航道通过能力,分析了内河交汇段船舶流特性。讨论了可接受间隙理论在内河交汇段实行"分道通航"规则下分析应用的可行性。借鉴公路无信号交叉口通过能力计算方法建立交汇段航道通过能力计算模型。以长江尹公洲"十字型"交汇航段为例,在条件相同下计算比较交汇段航道、基本段航道和船闸三种航段的通过能力。比较结果表明:交汇段通过能力小于基本段通过能力,但大于船闸通过能力;为内河航道设计、交通运输规划等相关领域的人员提供参考。

In order to study the channel passing capacity of the waterway intersection, the flow characteristics of waterway intersection vessels is analyzed. The feasibility of using gap acceptance theory in the waterway intersec- tion is discussed which under the branch channel rules. Learned from the calculation methods of the passing capaci- ty of highway unsignalized intersections the channel passing capacity＇ s calculation model of the waterway intersec- tion is established. Three kinds of passing capacities --waterway intersection, basic segment and shiplock under the same conditions on Yingongzhou section of the Yangtze River are calculated. The comparison results show that：the passing capacity of waterway intersection is less than the basic segment, but greater than shiplock＇ s, which can pro- vide a reference for the field of inland waterway design and transportation planning.
