Abstract

Abstract: Many diseases appeared in the operation stages of domestic concrete-filled steel tubular ( CFST) arch bridges， including debonding between steel tubular and concrete，corrosion，part deformation of tubular，corrosion and rupture of suspender as well as strong vibration． And then the disease causes were discussed from the aspects of structure，material， construction，maintenance and mechanics． Finally，some design suggestions on CFST arch bridge are proposed．

Key words: concrete-filled steel tubular ( CFST) , arch bridge, diseases, causes, design suggestion

摘要： 针对钢管混凝土拱桥出现的管内脱空、钢管锈蚀与局部变形、吊杆锈蚀与断裂、桥梁振动强烈等常见病害，从拱桥构造、材料、施工、养护和力学等方面分析了病害成因，提出了今后钢管混凝土拱桥设计的建议。
