Abstract
Gechougou Bridge with 136m span is a simply supported concrete-filled steel tube tied-arch bridge in railway. The dumbbell-shaped open web section was adopted for its arch rib, and it was the firsttime to use this kind of arch rib section for concrete-filled steel tube tied-arch bridge of railway. Through comparative analysis on several typical arch rib sections, this reasonable structural form and sectional dimensions of arch rib were obtained for the usage of concrete-filled steel tube tied-arch bridge with long-span in railway.关键词
