【摘要】 基于不同典型航道的航道尺度与通航条件对通航船舶尺度的影响，从航道宽度、水深和净空高度3个层面，结合时变的风、流条件，构建了多通航环境因素影响下的大型船舶通过典型航道的允许尺度数学模型，运用Visual Studio 2022开发了航道通过大型船舶尺度的计算软件并进行实例计算，可实现长江干线长河段航道通过大型船舶的能力实时预判。文中研究成果对航道主管机关现场监管、航运企业运营调度、引航机构精准服务均有重要的参考作用，有利于避免船舶堵塞航道的事故发生。更多还原

【Abstract】 Based on the influence of channel scales and navigation conditions of different typical waterways on navigable ship scales, this paper constructs a mathematical model of allowable scale for large ships passing through typical waterways under the influence of multiple navigable environmental factors from three aspects: channel width, water depth and clearance height, combined with time-varying wind and flow conditions.Visual Studio 2022 is used to develop the calculation software of waterway through large ships and carry out the example calculation, which can realize the ability prediction of waterway through large ships in the long section of the Yangtze River trunk line.The research results of this paper have an important reference role for the on-site supervision of the competent authorities, the operation and scheduling of shipping enterprises, and the precise service of pilot agencies, It is helpful to avoid the accident of ship blocking the channel.更多还原
