摘 要:跨越航道建筑物的通航净空高度是《海轮航道通航标准》的一项核心内容。船舶水线以上高度是通航净空高度计算的关键参数。《海轮航道通航标准》制订过程中,根据各类营运中实船的数据,按一定的保证率进行统计分析,确定了各类船舶的空载营运状态下实际吃水与满载吃水的合理比值。按照该比值计算了全球现有实船航行时水线以上高度。同时结合调研国内外桥梁资料,确定《海轮航道通航标准》采用的船舶水线以上高度表。内容系统全面,对跨越航道建筑物设计和建设以及保障通航安全具有重要意义和深远影响。The navigation vertical clearance ofbuildings across waterways is a core content of the Navigation Standard of Waterways for Seagoing Vessel. The vessel height above the waterline is a key parameter for the calculation of navigation vertical clearance. During the formulation of the Navigation Standard of Waterways for Seagoing Vessel,a statistical analysis is carried out according to a guarantee rate with the data of various types of vessels in operation, and the reasonable ratio of ballast draft to loaded draft is determined for the vessels. The height above the waterline is calculated for existing vessels in the world according to the ratio. At the same time, the table of vessel height above the waterline adopted in the Navigation Standard of Waterways for Seagoing Vessel is determined depending on the research on bridges at home and abroad. This study is systematic and comprehensive, filling the domestic gap in the field, and is of great significance for and far-reaching influence on the design and construction of buildings across waterways and the protection of navigation safety.
