盐宝线限制性航道通航安全仿真研究

盐宝线扬州段存在众多老旧桥梁;且由于资金短缺导致桥梁短期内难以拆除改建,老旧桥梁将长期影响盐宝线扬州段航道船舶的通行安全。基于盐宝线扬州段航道现状,在对盐宝线扬州段船舶安全通航研究分析的基础上,结合道路交通信号灯启示,对缺乏调度控制上行船舶开展分散控制研究;并构建多节点航运调度仿真模型,分别对航道现行以及对上行船舶分散控制后的调度方案进行仿真研究。结果表明:在优化方案下,下行船舶通过盐宝线扬州段平均耗费时间由42.52 h缩短为42.48 h,而上行船舶通过盐宝线扬州段平均耗费时间9.11 h增加为10.36 h。在优化方案下,上、下行船舶在桥区航道拥堵风险比在现行调度方案下有明显降低,拥堵风险指标由585次/d降为0次/d。

Research on Simulation of Navigation Safety of Restricted Channel in Yanbao Waterway of Yangzhou Segment

There are many critical nodes such as the Baoying lock and many old bridges in Yanbao waterway of Yangzhou segment, it is difficult to torn down and rebuilt due to a shortage of fund, and it will impact Safe navigation of the ship in Yanbao Waterway of Yangzhou Segment in a long time. Based on the channel condition of Yanbao waterway of Yangzhou segment, the analysis of ship safety navigation, and the revelation of road traffic lights, A joint simulation scheduling model of multi-bottleneck is established, which study current and optimized scheduling scheme respectively. The simulation results show that the optimized scheduling scheme is workable and the risk of channel congestion is reduced effectively.
