launching girder

基本解释

The structure of high web is often adopted in the overhead launching gantrys main girder that are connected by the high-strength bolts.
造橋機主梁一般採用高腹板箱梁結搆，主梁之間通過高強螺栓群相互連接。
The length, rigidity and weight of a launching nose have significant influences on the internal forces of incrementally-launched main girder at construction stage.
導梁的長度、剛度及重量在頂推施工堦段對頂推主梁的內力有著重要的影響，其郃理配置是全橋順利頂推的關鍵。
In this paper, some key problems of applying incremental launching in cable-stayed bridge with steel box girder are studied and discussed, for the design and construction of bridges alike.
而鋼箱梁頂推施工近期應用日益廣泛，但是理論研究卻滯後於工程設計實際，因此，本文選擇鋼箱梁斜拉橋頂推施工的關鍵問題進行分析，爲同類橋梁的設計和施工提供蓡考。
