目前,苏联内河水道趋向使用大船,而且大船尺寸接近于闸室尺寸,因此非常重视大船进(出)闸室时所出现的水力现象。新西伯利亚建筑工程研究所水工试验室进行了试验。试验设备见图1,设备的主要部分:闸室长150米、宽18米,闸室水深4.3米,引航道长800米。试验船为5000吨载货量的柴油机船、船长138.6米,宽16.5米,吃水3.5米。按弗劳德相似准则,根据引航道试验要求和现有场地面积确定模型比尺为1:50。
At present, the Soviet Union inland waterway tends to use large ships, and the large ship size is close to the size of the lock chamber. Therefore, it attaches great importance to the hydraulic phenomenon that occurs when large ships enter (exit) the lock chamber. Novosibirsk Institute of Building Engineering hydraulic laboratory conducted a test. Test equipment shown in Figure 1, the main part of the equipment: gate length 150 meters, width 18 meters, 4.3 meters deep water chamber, navigation channel 800 meters long. The test vessel is a diesel-powered 5, 000-ton cargo ship of 138.6 meters in length with a width of 16.5 meters and a draft of 3.5 meters. According to Froude’s similarity criterion, the scale of the model was determined to be 1:50 according to the pilotage test requirements and the existing site area.
