船行波对复式航道隔离带宽度的影响

复式航道是根据船舶吃水的不同将航道断面设计为深浅不同的阶梯形。由于小船的耐波性较差，大船航行时所兴起的船行波往往会引发小船横摇角的显著增大，影响安全。设计时可将两航道间留有一定的富裕距离（隔离带），以减少船行波的影响。通过数值计算和物理模型试验两种方法，分析研究了不同参数条件下，船行波对小船横摇角的影响，由此判断隔离带宽度能否满足要求。

Influence of ship wave on compound channel excess breadth

The compound channel is designed into different shadows of ladder-type according to different ship drafts.Small boats sail through the shallow side of the channel while big ships sail through the deep side.Because of the low ability in resisting wave,the small boat's swing angle tends to increase significantly by the big ship's wave.The excess breadth between ships is necessarily to be designed to reduce the impact of the ship wave.This paper analyzes the small boat's swing angle which is affected by the sh...
