| 摘 要： | 重载进出口船航行至长江口深水航道东端D12灯浮附近时,常感到有明显的横向流压。尤其是大潮汛、大风浪或鸡骨礁初涨水时,进出口船要预配10。甚至以上的风流压差,而且要加车航行,否则极易偏离航道压碰D12灯浮。此文分析长江口D12灯浮附近形成潮流的反射迴流和突变效应的原因及规律,并指出船舶在此水域航行时的注意事项,以引起航经船舶的注意。

The Reflection Backflow and Mutagenic Effects of Current near D12 Light Buoy |
| |
| Abstract: | Heavy load vessel sailing to the eastern end of deep-water channel near D12,ofen feels the obvious crosswise flowing pressure,especially,flood tide,big storm,early rising water of JIGUJIAO.The vessel inward must match 10 degrees even above in advance the angles of drifts.and add more speed,or vulnerable to touch light buoy D12.This paper analyses the reason caused by tidal reflection backflow around D12,and point out caution for ship passing there. |
