介绍了近代历史海图在港口航道工程中应用的一个实例。讨论了浙江虾峙门口外浅段航道自19世纪90年代至20世纪90年代期间各历史阶段的历史冲淤变化,表明该浅段航道是水深保持稳定且缓慢加深的良好航行通道。本项研究及其成果为宁波港和舟山港超大型船舶出海航道的选择提供历史依据。
An example of the application of modern history charts in port waterway engineering is introduced. The history of scouring and silting in the shallow channel of Shoushi gate in Zhejiang province from the 90s of the 19th century to the 90s of the 20th century was discussed. It shows that this shallow channel is a good navigation channel for steady and slow deepening of water depth. This study and its achievements provide the historical basis for the choice of the sea-going routes of super-large vessels in Ningbo Port and Zhoushan Port.
