悬栅消能工是将栅条悬空布置于泄水陡坡或消力池内的一种新型消能方式，为进一步研究新型悬栅消能工及其消能效果，通过物理模型对影响消力池消能效果的矩形悬栅布置形式进行试验。结果表明：消力池内布置悬栅对稳定水流和降低水深作用明显；由栅高hs、栅距bs、悬栅数量ns对池内最大水深hm影响得出栅高hs的适宜值为10 cm，栅距bs的适宜值为4～5 cm，悬栅数量ns的适宜值为16～20根；在Q＝15 L／s下，悬栅hs＝10 cm、bs＝4 cm、ns＝20根的布置形式可将消力池最大水深降低4．97 cm，降幅高达15．84％。“,”Energy dissipater suspension gird is a new type of energy dissipation hanging the grid strips on sluicing steep slope or in stilling pool. In order to further study on the new energy dissipation suspended grid and its effect of energy dissipation,effecting the stilling pool energy dissipation of rectangle suspended grid layout pattern was performed by physical model. The results show that suspension gird arranged in the stilling pool has obvious effect on steadying water flow and reducing the depth of water;by the effect of suspension gird high hs , suspended grid spacing bs and suspension grid number ns on the maximum water depth hm in stilling pool can be drawn suitable values of suspension gird high hs for 10 cm,suitable values of suspended grid spacing bs for 4-5 cm and suitable values of suspension grid number ns for 16-20;under the water flow Q=15 L/s,the layout pattern of suspension grid hs=10 cm,bs=4 cm,ns=20 can reduce the maximum water depth of stilling pool by 4.97 cm,decreasing water depth as much as 15.84%.
