摘　　要：某电厂钢结构栈桥单件跨度长,高度高,重量大,鉴于现场施工场地狭窄,施工单位间交叉作业多,通过吊装经济性比较,选择钢桁架组装、布置及吊装工艺,对钢桁架采用附臂式吊机整体抬吊就位,保证了工程质量,节约了工期。Single piece of steel structure trestle in a power plant is high and heavy and has long span. Considering the narrow construction site of coal trestle and complex cross construction, steel truss assembly, positioning and lifting processes are selected after comparison of economical performance among various lifting processes, and arm-attached crane is used to realize integral lifting and positioning of steel truss. Construction quality is successfully guaranteed and construction schedule is shortened.
