摘　　要：包西铁路黄河特大桥施工中,成功利用现有的设备器材组成提升吊机、悬拼吊机等设备,进行钢桁梁的悬拼作业。严格按照钢桁梁的预拼、悬拼及高强螺栓施拧工艺进行钢桁梁各杆件的安装,确保了施工安全、质量和进度。In the construction of the super bridge across the Huanghe River, we have succeeded in using existing equipment and apparatus to form the equipments such as crane, hoister etc. and proceeded with suspended assembling of steel truss. We have installed the member bars of the steel truss strictly according to the techniques of prescrambling, suspended assembling, and tightening of high strength bolts, thus we have ensured the safety, quality and progress of the construction.
