摘　　要：微山三线船闸工程位于京杭运河干线通道和南水北调工程东线输水线路上,需平衡高效通航与节约用水的目标。针对闸室平面尺度与船闸通过能力、过闸用水量计算的问题,在分析设计水平年过闸艘次比、船型尺度的基础上,根据主力船型尺度,提出不同的闸室平面尺度方案,开展船闸通过能力和用水量计算,得出船闸通过能力、用水量与闸室平面尺度的定量关系。结论是微山三线船闸的通过能力随闸室平面尺度增大而增大,但增幅不同,船舶过闸用水量不随闸室平面尺度增大而增大,因此有必要开展闸室平面尺度论证,微山三线船闸工程闸室平面尺寸宜取34 m×280 m。微山三线船闸工程闸室平面尺度确定方法对类似工程建设及规范修编具有积极借鉴意义。The Weishan Third Line Ship Lock Project is located on the main channel of the Grand Canal Link and the eastern water transmission line of the South to North Water Diversion Project,and needs to balance the goals of efficient navigation and water conservation.To the problem of calculating the plane scale of lock chamber and the capacity of ship lock chamber and the water consumption of lock chamber,based on the analysis of the ship-to-ship ratio and ship-type scale in the design level year,this paper puts forward different lock chamber plane scale schemes according to the main ship-type scale,and carries out the calculation of the lock carrying capacity and water consumption to obtain the quantitative relationship between lock carrying capacity,water consumption and lock chamber plane scale.The conclusion is that the passing capacity of Weishan Third Line Ship Lock increases with the increase of the lock chamber plane scale,but the increase is different.The water consumption does not increase with the increase of the lock chamber plane scale.Therefor,it is necessary to conduct a plane scale demonstration of the lock chamber.The plane size of the lock chamber for Weishan Third Line Ship Lock Project should be 34 m×280 m.The method for determining the plane scale of the lock chamber in the Weishan Third Line Ship Lock Project has positive reference significance for similar engineering construction and standard revision.
