Abstract

Abstract: A deck type bridge constructed with reinforced concrete has diferent arch axes between design and actual construction． The efects of deformation and intemal forces produced by transverse bias of arch axis are analyzed by simulative computing． Several measures used to improve the statements of mmn box-ribbed arch under loading are presented ．These methods could be used as a reference to improve．repair and strengthen the similar arch bridges having initial bias arch ring in future．

Key words: reinforced concrete, box-ribbed arch bridge, arch axis, bias , arch strengthen

摘要： 针对某上承式钢筋砼箱板拱桥建成后的拱轴线与设计拱轴线发生横桥向偏离，通过计算仿真分析探讨拱轴线偏离对主拱内力和变形的影响，提出了几种改善主拱受力状态的措施，为同类拱桥的施工偏差和加固维修提供借鉴.
