摘　　要：桥梁布设在通航水域的桥墩以及通航孔在一定程度上限制了船舶的航行,划定桥区水域对指导船舶安全航行具有重要意义。通过梳理当前桥区水域法规中船舶航行限制,分析划定桥区水域的影响因素;以桥梁涉水桥墩对航道内在航船舶的影响为依据,基于船舶领域理论设计了桥区水域宽度和纵向长度计算方法,可依据桥梁特点及航道水域特征对桥区水域进行划定,实现桥区水域划定的一桥一策;利用该方法对长江某大桥的桥区水域进行划定。结果表明,与传统桥区水域划定方法相比,该划定方法能够在保障船舶桥区航行安全的基础上,减少对航道内正常航行船舶的约束,同时可避免岸线资源的浪费。The piers and navigable holes of bridges arranged in navigable waters limit the navigation of ships,and thus the demarcation of bridge area scope is of great significance to guide the safe navigation of ships.We analyze the influencing factors for the bridge area scope delimitation by sorting out the navigation restrictions in the current bridge area laws and regulations.According to the influence of the bridge piers on the navigating ships in the waterway,we design the methods for calculating the width and length of the bridge area scope based on the ship domain theory,which can demarcate the bridge water area scope according to the bridge and waterway characteristics,and realize the one bridge one policy.The method is used to demarcate the bridge area scope in the Yangtze River.The results show that compared with the traditional method of bridge area scope demarcation,the method proposed in this paper can not only ensure the safety of ships sailing in the bridge area but also reduce the navigation constraints of the ships near the bridge while avoiding the waste of shoreline resources.
