船闸集中输水系统复合阻力系数的试验研究

Test and Research on Composite Resistance Factors for Concentrated Filling System of a Lock (continued)

针对集中输水系统中典型的有、无消能室的平底环形短廊道的情况,进行当圆弧内侧曲率半径R内与廊道宽度b的比值分别为0.25、0.5、1.0时,阻力系数ξ与几何尺度(l/b、L/b、r/b、ω出/ω计、ω消/ω出)的关系的研究,同时提出有关设计原则和对规范有关内容的修改建议。

In view of the structural features of concentrated filling system, which takes a form of flat bottom circular culvert with or without energy-dissipating room, this paper makes investigation 011 the relationship between resistance factor ξ and geo metrical dimensions(l/b, L/b, r/b, ωoutlet/ωcalculated, ωenergy-dissipating/ωoutlett), when the speeific values of inner curvature radii R to the widths of culvert b are .25, 0.5, 1.0. Some suggestions are also put fonvard to the design principles and revision to some articles in the design code.
