摘　　要：倒虹吸作为工程量小、施工方便的交叉输水建筑物,在我国输水工程中有着广泛应用。常见倒虹吸的管道尺寸较小,关于大孔径倒虹吸的结构研究较少。以某大孔径倒虹吸为例,对水平段的静力特性进行有限元数值模拟研究,通过对比不同工况下的不同荷载组合结果,分析倒虹吸结构的应力应变,得到倒虹吸结构应力和变形的分布规律,并验证大尺度下倒虹吸结构强度是否满足规范要求。As a cross water conveyance building with small engineering quantity and convenient construction,inverted siphon is widely used in water conveyance projects in China.The pipe size of the common inverted siphon is small,and the structure of the large-aperture inverted siphon is rarely studied.In this paper,taking a large aperture inverted siphon as an example,the static characteristics of the horizontal section are studied by finite element numerical simulation,and the stress-strain of the inverted siphon structure is analyzed by comparing the results of different load combinations under different working conditions,and the distribution law of stress and deformation of the inverted siphon structure is obtained,and the strength of the inverted siphon structure at a large scale is verified to meet the requirements of the code.
