摘要
为更好地描述内河航道的交通状况与通过能力的关系,引入航道服务水平和服务交通量的相关概念,探讨航道服务水平的确定方法,建立以船舶行驶自由度和航道饱和度为评价指标的指标体系,并结合航道实测交通流数据进行评价验证。评价结果表明:实例航道的运行状态在两个时间段的服务水平为二级,其余时间段为一级,计算等级与主观评价结果一致。因此,该评价体系能够真实反映航道的运行质量,可为航道设计和管理人员提供参考。
In order to better describe the relationship of traffic status and carrying capacity in inland waterways, the concept of waterway service level and service traffic volume is introduced to study the determination method of inland waterway service level and to establish an index system taking the degree of freedom of shipping and the degree of occupancy of waterways as the evaluation index, which is then evaluated and verified in combination of the measured traffic flow in the waterways. The evaluation results show that the service level of the evaluated waterway is second-level in two time quantum and first-level in others, which accords with the subjective assessment results. Therefore, proposed evaluation system can truly reflect the real status of waterway and can provide references for waterway designers and managers.
