摘要
我国内河水域新建桥梁在对主墩进行施工过程中,为了确保船舶正常通航,海事部门要求实行单向通航。因此,主墩施工期间桥区水域可能出现船舶排队等候过桥的现象,船舶等候过桥势必增加桥区水域复杂的通航环境,目前海事部门规定桥区水域(单向通航)航行的船舶之间应保持足够的安全距离。通过建立数学计算模型对桥区水域(单向通航)通航船舶之间安全距离进行量化研究,探讨出桥区水域船舶之间安全距离计算方法。为海事部门制定桥区水域通航安全管理规定、维护桥区水域良好的通航秩序和船舶过桥安全提供科学的理论依据。
During construction of the main bridge pier in inland waters in China, to guarantee the normal ship navigation, the maritime administration requires one-way traffic. Therefore, during construction of the main pier bridge, ships possibly wait to cross the bridge, and thus inevitably result in the complex navigation environment in the bridge area. At present, enough safety distance between ships is specified by the maritime administration department, A quantitative study on ship navigation safety distance is carried out by establishing a mathematical calculation model of bridge waters （one-way navigation） to provide a scientific theory basis for the maritime administration to work out the navigation safety management regulations and guarantee the safety of navigation environment.
