船闸运行状态与通过能力仿真分析

Analysis of shiplock operation and throughput capacity based on traffic simulation model

  • 摘要: 为定量分析和预报船闸的运行状态并指导其交通调度,基于Arena离散事件仿真平台,以湘江长沙枢纽双线船闸为例,通过已有研究成果建立船闸交通仿真模型,经实际资料验证该模型的可靠性,并分析了船闸在不同交通调度方案下的运行状态参数及最大通过能力。仿真分析结果表明,只有提高每个闸次的闸室利用率,才能有效增加船闸的通过能力;每个闸次的船舶艘数越多,一次过闸时间就长,平均延误就长。运行实践中可根据船闸状态和过闸交通需求,合理进行交通调度,在保障过闸安全的前提下协调船闸通过能力与船舶延误之间的关系。借助仿真输出的运行状态参数,有助于充分掌握船闸系统的交通规律,分析不同设计水平下的船闸最大通过能力,或是视不同交通负荷预选调度方案,综合提高过闸能力与服务质量。

     

    Abstract: In order to quantitatively analyse and predict the shiplock operation conditions and give some guidances in the lock scheduling, a traffic simulation model for a double-lane lock was developed based on the discrete event simulation platform of Arena. Taking the double-lane lock of the Changsha hydroproject located at the Xiangjiang River as a case study, the operation state parameters and the maximum throughput capacity of the Changsha lock were simulated and analyzed under different traffic scheduling modes and working conditions, and the reliability of the simulation model was validated by the measured operation data. The simulated results show that the utilization rate of the lock chamber is only improved in each lockage time and that the lock throughput capacity can effectively increase. The greater the number of ships in the lock chambers for each lockage time is, the longer the lockage time and the mean delay are. From the engineering practices it is found that the relatioships between the lock throughput capacity and delays can be coordinated and the navigation lock scheduling can be optimized under the conditions of protection of the lockage safety, according to the traffic demands and the lock working conditions. With the operation state parameters given by the simulation model, which can help to fully grasp a traffic law of the lock system, the lock maximum throughput capacity at different design levels are analyzed or the lock scheduling programs are optimized in dependence on different traffic loads to improve the lock throughput capacity and the quality of service.
