This paper is a deep and careful research on the effective width of artificial dredging water way on the basis of domestic and international relevant researches and the condition of port, ship and shipping management development. It takes great consideration and careful calculation on data of dredging waterway, ship drift multiple and the choice of leeway and drift angle. And make a comparison and test with the leeway and drift angle and ship drift multiple in "standard of general port layout". Therefore, it does a research and retest to the standard content and raised some suggestion. It is a useful experience for planning of waterway and it combines scientific research with social productive practice. It serves for social production and makes profit. |
