摘　　要：随着建筑业的高速发展,工业与民用建筑矩形钢管混凝土结构工程的应用越发广泛。在不同施工条件下,矩形钢管混凝土结构施工方法亦多种多样,其中钢柱内腔混凝土浇筑施工中有高抛法和顶升法两种施工方法。本文通过分析矩形钢管混凝土柱高抛与顶升施工的机理,结合实际施工验证在矩形钢管混凝土柱高抛自密实混凝土施工技术具有较高的经济效益。With the rapid development of construction industry,rectangular concrete filled steel tubular structures are more and more widely used in industrial and civil buildings.In different construction conditions,there are various construction methods of concre-flled rectangular steel tubes,including high casting method and jacking method.In this paper,by analyzing the construction mechanism of concrete-filled rectangular steel tube column,the high-throw and self-compacting concrete construction technology of concrete-filled rectangular steel tube column is proved to have higher economic benefits.

关 键 词：矩形钢管混凝土结构 高抛法 顶升法 机理分析
