摘要
考虑到绞吸式挖泥船输送系统中泥浆摩擦阻力损失计算所采用的达西-魏斯巴赫(Darcy-Weis-bach)方法在理论上只适用于特定的条件,在实际的应用中误差较大,结果的可靠性低。针对此局限性,提出了适合于绞吸式挖泥船管路特性的摩擦阻力损失计算方法,实际应用表明新的计算方法能够满足工程需要。
The formula of Darcy-Weisbach is often applied to calculate the loss for friction in the pipeline of a cutter suction dredger transportation system. This calculation method can only be applied to specific condition in theory and has errors in practical range,reducing the reliability of the results. Considering this limitation, a formula of the loss friction resistance for a cutter suction dredger was presented. Practical use showed that the new method of calculation could meet the needs of practical engineering application.
