摘　　要：介绍了船闸复合管直角边缘单支孔充水阻力系数试验的主要结果。包括：阻力系数影响因素分析，模型设计、试验和对试验结果的讨论；在此基础上，拟合了计算直角边缘单支孔充水阻力系数的经验式。Model tests are conducted to investigate the resistance coefficient of square-edged single-port in filling operation. On the basis of model test, an empirical formula for the resistance coefficient of square-edged single-port in filling operation is derived and technical data are provided for the design and computation of lock filling and emptying system.
