摘要
赣江尾闾西支属典型弯曲河段,受桥梁建设、右岸挑流及回旋水域占用主航道等因素影响,局部通航条件存在一定安全隐患。为提升汇贤大桥上游航段的通航安全性,提出将现状航道线向左岸调整至接近河道中心线略偏右侧位置,并对局部不满足水深要求区域实施疏浚。本文对航道调整方案进行了数值模拟。结果表明,调整方案可优化弯曲河段的局部航道走向,保障船舶通航安全,同时对该河段整体水流运动特性的影响较小,工程干扰程度有限。
The lower reaches of the West Branch of the Ganjiang River are typical meandering river sections.Influenced by bridge construction,flow deflection on the right bank,and the occupation of the main channel by turning areas,there are certain safety hazards in local navigation conditions.To improve the navigation safety of the section upstream of Huixian Bridge,it is proposed to adjust the existing channel line to a position slightly to the right of the river centerline and to dredge areas that do not meet the depth requirements.Numerical simulations were conducted for the channel adjustment plan.The results show that the adjustment plan can optimize the local channel direction of the meandering river section,ensure the safe navigation of ships,and has a limited impact on the overall flow characteristics of the section,with a low degree of engineering interference.
