摘　　要：北京奥林匹克公园瞭望塔属柔性超高层钢结构建筑,高度达248m,结构形式复杂,构件数量多;经拼装方案比选,确定了塔身筒体地面拼装模块式吊装单元体,塔冠地面拼装树枝状吊装单元钢结构拼装技术,减少了高处作业工作量,节省了高处吊次,缩短了工期,确保了工程质量和安全,为类似工程施工积累了宝贵经验。The 248m-high sightseeing tower in Beijing Olympic Park is a superhigh flexible steel structure with complex figure and numerous components; after comparison among assembly schemes, the steel structure assembly technique of tower body tube ground assembly modular hoisting unit plus tower top ground assembly branch-type hoisting unit is adopted to reduce aerial workload and aerial hoisting times, shorten construction schedule and ensure engineering quality and safety. Precious experiences have been cumulated for construction of similar projects.
