摘　　要：南水北调中线工程是世界上特大型的跨流域调水工程,漕河渡槽是总干渠上的一座重要的输水建筑物。渡槽桁架拱的预制和吊装是施工的技术难点和关键工序之一。依据该工程的施工环境,对桁架拱的预制方案、场地布置、吊装设备、吊点布置、拱片运输安装方法及应注意的问题进行了分析论述,提出了既经济又可行的施工方案。可为类似工程提供有益的借鉴。The mid line of the project for transferring water from South China to North China is a great project in the world, which crosses different valleys. The Caohe Bridging Gutter is an important water-transferring project in the whole aqueduct. The pre-casting and erection of the braced arches are the technical difficulty and are of the greatest importance among all the working procedures. According to the specific engineering conditions, the paper makes a study of the pre-casting plan, site layout, hoisting equipment, layout of hoisting spots, transporting and fixing methods and other important points for attention, on basis of which an economical and practicable construction plan is brought forward. The construction plan may be of beneficial referential value for similar projects in future.
