一、运河的尺度通过能力和船数通过能力 尺度通过能力 主要取决于运河的尺度,即水深、宽度、边坡、水下横断面面积和曲率半径。运河尺度和通航运河的船舶尺度(如吃水、船宽和船长等)有着密切的互为因果的关系。确定运河尺度时, First, the scale of the canal Through capacity and number of ships through the ability to measure the ability to pass depends mainly on the scale of the canal, namely, water depth, width, slope, underwater cross-sectional area and radius of curvature. The scale of the canals and the navigable canals (such as draft, breadth of ships and captains) have a close causal relationship with each other. When determining the scale of a canal,
