摘　　要：对南水北调肖河涵洞式渡槽工程进出口连接段进行了多种方案的试验研究。试验结果表明，在两轴线正交状态下，进出口连接段型式的改变都难实现涵洞进出口水流的平稳顺畅。最终选定肖河涵洞轴线与肖河河道主流平行，与总干渠渡槽轴线成75°交角。The various schemes were studied on the connection section of the exit and entrance at the Xiaohe culvert aqueduct in the South-to- North Water Diversion Project. The results showed that when the two axes were orthogonal,the change of the connection section types of the exit and entrance could not ensure water to flow steadily and smoothly. At last,we chose the Xiaohe culvert aqueduct was parallel with the Xiao- he River＇s course, creating 75° with the axis of the general main canal of the South-to-North Water Diversion Project.
