摘要
由于兰江铁路桥通航尺度不满足三级航道的通航安全要求,为了研究兰江铁路桥桥区通航水流条件,该文章收集了相关资料,分析了工程河段河道演变及水流条件,建立并验证了适合该区域的二维水流数学模型,通过模型对兰江铁路桥桥区的通航水流条件进行计算分析,得出兰江铁路桥桥区的航道通航水流条件,并提出相关的安全保障措施,以保障船舶航行安全,对今后类似现状航道及桥区通航安全有一定的借鉴作用。
Since the navigation scale of Lanjiang Railway Bridge does not meet the navigation safety brought about by the requirements of the three-level waterway,in order to study the navigable flow conditions of Lanjiang Railway Bridge area,this paper collected relevant data,analyzed the channel evolution and flow conditions of the project reach,and established and verified a two-dimensional flow mathematical model suitable for this area.The navigable flow conditions of Lanjiang Railway bridge area are calculated and analyzed by the model,and the navigable flow conditions of Lanjiang Railway bridge area are obtained,and relevant safety measures are proposed to ensure the navigation safety of ships,which has a certain reference role for the navigation safety of similar current waterways and bridge areas in the future.
