摘要
文中以铁铺水道至道人叽水道为研究区域,构建了蜿蜒河流船舶交通波模型,基于格林希尔茨速度-密度关系曲线,计算了不同时期(洪水季、枯水季)船舶集散波波速.结果表明:随着蜿蜒河段的长度及蜿蜒程度的增大,船舶排队时间和排队距离逐渐增加;枯水季船舶排队时间和排队距离分别为洪水季船舶的1.53倍和2.58倍.考虑到经典格林希尔茨关系与文中研究水域船舶速度-密度曲线的差异,船舶排队相关结果较实际情况偏大.
Taking Tiepu Waterway to Daorenji Waterway as the research area,the ship traffic wave model of winding river was constructed.Based on Greenhill’s velocity-density curve,the wave velocities of ships in different periods(flood season and dry season)were calculated.The results show that with the increase of the length and winding degree of the winding river section,the queuing time and distance of ships gradually increase.The queuing time and distance of ships in dry season are 1.53 times and 2.58 times that of ships in flood season respectively.Considering the difference between the classical Greenhill’s relation and the ship speed-density curve in the waters studied in this paper,the related results of ship queuing are larger than the actual.
