钢箱梁结构因其自身的特性在市政工程建设得到大量运用,钢箱梁吊装施工中空间就位及空形态的控制问题较为突出,其中带纵坡的弧形钢箱梁通过旋转结构找横坡就使得钢箱梁在施工过程中整体空间形态要有控制技术难度更高,极易造成钢箱梁支座托空。该文结合工程实例,就有纵坡且旋转结构找横坡弧形钢箱梁吊装后产生支座托空的处理措施进行论述。
鋼箱樑結構因其自身的特性在市政工程建設得到大量運用,鋼箱樑弔裝施工中空間就位及空形態的控製問題較為突齣,其中帶縱坡的弧形鋼箱樑通過鏇轉結構找橫坡就使得鋼箱樑在施工過程中整體空間形態要有控製技術難度更高,極易造成鋼箱樑支座託空。該文結閤工程實例,就有縱坡且鏇轉結構找橫坡弧形鋼箱樑弔裝後產生支座託空的處理措施進行論述。

Steel box girder structure is widely applied nowadays for its virtues, but the controlling problems in space location and spatial form in its con-struction are severe, and the finding of cross slope through rotating structure by arc steel box girder with longitudinal slope renders controlling technology of steel box girder over spatial form harder, easily causing empty bearing of steel box girder. The treatment measures for such problem are presented in de-tail.
