The middle of the chief navigable channel of a waterway that forms the boundary line between states. 形成国家之间的边境线的水路上的主要航行路线的中间部分。
In developing the design vessel distribution, the designer should first establish the number and characteristics of the vessels using the navigable waterway or channel under the bridge. 在研究设计船只分布时,设计者宜首先确定使用桥下水道或航道船只的数量和特性。
Navigable Condition Testing by Small Scale Ship Model in Regulation of Shoaly Waterway between Chongqing and Luzhou in Changjiang River 长江渝泸段滩险整治小尺度船模通航试验研究
Improving the navigable capability of waterway, it is necessary to study the changes of hydrodynamic condition and to predict the amount of sediment deposition in the dredged channel. 而浚深航道以提高通航能力,需要研究海域水动力变化并预测疏浚槽的回淤。
Based on The silt carrying capacity, pick-up velocily and braking velocily this paper gives forth the computing expressions of regulation width for a navigable waterway, and then makes derivation on the discrimination number for a river model test. 本文根据河流挟沙能力、起动和止动流速推导得航道整治线宽度计算公式,并据此衍生得河工模型试验判数,可供有关人员参考。
Calculation Method of Clear Width of Bridge on Bend Navigable Waterway 弯曲河道上桥梁通航净宽的计算方法探讨
Since having been put into use, VTS has effectively improving the traffic environment of the port and navigable waterway, and enhancing the safety of the water. VTS投入使用以来,有效地改善了所在港区和航道的通航环境,增强了水上交通安全。
