摘要
福清跨越龙江斜独塔斜拉桥桥长175m,采用105m+70m斜独塔单索面结构,主梁为预应力混凝土大悬臂单箱三室结构,桥塔采用沿纵向变厚度矩形结构。采用MIDAS 2010程序对桥梁结构稳定性进行了分析,为同类型桥梁结构设计提供参考。
The inclined single -tower cable -stayed bridge crossing Lung- chiang in Fuqing is 175m long, which adopts 105m ＋70m inclined single -tower single cable plane structure. The main beam is with prestressed concrete large cantilever single -box three -chamber structure, and the bridge tower adopts the structure of following longitudinal varying thickness rectangle. The analysis on stability of bridge structure is made by adopting MIDAS 2010 procedure, providing reference for structure design of similar bridge.
