【摘要】 经2014～2016年实测航道底高程数据对比,铜鼓航道现状主槽内断面平均年淤强在0.23～1.52m/a之间。数学模型试验成果反映出,二期航道工程建设后大部分航段的轴线与涨落潮流主流向夹角较小,垂向无不良回流与乱流,除口门段和转弯段外,大部分航段横流小于0.50 m/s。百年一遇洪水和强台风作用下,均未形成碍航性骤淤。更多还原

【Abstract】 According to real measured data on the channel bottom elevation from 2014 to 2016, annual average sedimentation rate is 0.23～1.52 m/a for the cross section of main channel. The numerical model test results show small included angle between the channel axis and the direction of flood and ebb tide after the construction of phase-2 channel, no adverse undertow and turbulent flow along vertical direction, and the transversal current of0.50 m/s or less for most part of channel except for estuary and tuning section. No sudden sedimentation that affects navigation is caused by 100-year-return flood or strong typhoon.更多还原
