本文根据实地调查,总结了河套灌域闸下消能的成熟经验和存在的问题。在⊿H≤1.60mg≤1.50m~3/s-m 和⊿H≤0.30m、1.500.30m、g>1.50m~3/s-mF_■=2.5～4.5条件下的水闸则尚不能满足防冲的要求,有待进一步研究。
Based on field investigation, this paper summarizes the mature experience and existing problems of energy dissipation under floodgates in Hetao irrigation area. In the range of ⊿H≤1.60mg≤1.50m ~ 3 / sm and ⊿H≤0.30m, 1.50 0.30m and g> 1.50m ~ 3 / s-mF_ ■ = 2.5 ~ 4.5 can not meet the requirements of anti-stamping for further study.
