摘　　要：倒虹吸管是输水工程中常见的交叉建筑物,设置在渠道与河流、谷地、道路相交处的压力输水建筑物。当渠道通过山谷、溪流,因谷道深邃、渡槽排架过高难以修建渡槽,或需高填方,或采用绕线方案有困难时,经过经济技术比较,可采用倒虹吸管的方案。倒虹吸管具有工程量少、施工方便等优点,在山区的输水工程中有着广泛的应用。依托枫木河水库的输水工程,介绍倒虹吸管的布置型式、水力计算和结构分析。Inverted siphon is a common pressure water conveyance structure in water conveyance engineering,which is set at the intersection of channel and river,valley and road.When the channel passes through valleys and streams,it is difficult to construct the aqueduct because of the deep valley,the high bent of the aqueduct,or the high filling is required,or it is difficult to use the winding method,the scheme of inverted siphon can be adopted after economic and technical comparison.Inverted siphon is widely used in water conveyance projects in mountainous areas due to its advantages of small quantity and convenient construction.Based on the water conveyance project of Fengmuhe Reservoir,this paper introduces the layout pattern,hydraulic calculation and structural analysis of the inverted siphon.
