| 摘 要： | 船闸引航道口门区是船舶进出船闸的＂咽喉＂,受特殊边界条件的影响,该区域内产生有斜流、横流及回流等不良流态,对船舶安全航行造成很大影响。文中从理论上分析了口门区内不良流态对船舶航行的影响关系及导流墩削弱口门区内斜流和回流、改善通航水流条件的机理。结果表明,导流墩或导流墩与其他工程措施的结合应用是改善口门区水流条件的有效工程措施。

| Abstract: | Entrance area of shiplock approach channel is the throat for the navigation of ships.With the influences of special boundary conditions,there is a great deal of flow patterns such as inclined flow,crossflow and reflux at the entrance area,which cause a big influence for navigation safety.This paper analyses the effect of the bad flow patterns at the entrance area on ship navigation,and the improvement mechanism of flow conditions by diversion pier to weaken the inclined flow and reflux at the entrance of ap... |
