摘要
结合云南某新建铁路劲性骨架混凝土拱桥实际,针对劲性骨架吊装、拱肋混凝土浇筑和拱上结构施工的工程特点,对大跨度缆索吊装体系进行初步设计,确定了缆索吊的基本参数,通过荷载计算,对主索等关键结构和部件进行分项设计,可为类似工程提供参考。
Taking a Concrete-Filled Steel Tubular Stiffening Frames Reinforced Railway Arch Bridge in Yunnan as exam- ple, in view of the engineering features of rigid frame arch rib hoisting, concrete pouring and arch structure, preliminary design of the large-span cable-hoisting system is carried out, which determines the basic parameters of cable crane. Sepa- rate design of key structures and components through the load calculation, which provides reference for similar projects.
