(一)任务的提出 航道水深设计尺度受到船舶航行下沉值的影响。近几年通过试验得到了一些关于航行下沉值的单个数据,从这些试验数据中可以看出航行下沉这个过程所具有的重要意义。但是,至今仍缺乏把航行下沉作为航道 (A) The task proposed The design of waterway depth is affected by the sailing value of the ship sailing. In recent years, some experiments have been carried out on a single data about sailing values. From these experimental data, we can see the significance of this process of sailing. However, there is still a lack of navigational sinking as a waterway
