摘　　要：峡江水利枢纽工程预制梁架设施工现场条件复杂,不具备预制梁吊装条件,无法形成坝顶运梁道路,需架设贝雷架作为临时通道。介绍了峡江水利枢纽工程坝顶混凝土预制梁架设的施工技术,从方案选择、架桥机选型以及架设过程中各项技术措施的落实等几方面阐述了坝顶预制梁架设的特点和技术要点。Because of complex construction site conditions in erecting of prefabricated girder in Xiajiang Hydro-junction project to have no method to build road for transporting the girder,which result in the girder cannot be hoisted,so the Bailey truss need to be erected as the temporary road.This paper introduces erection technology for concrete prefabricated girder at the top of dam in Xiajiang Hydro-junction project,and shows characteristics on prefabricated girder erection from the aspects of scheme selection,selection of bridge erecting machine and erection process,etc.
