Abstract

Abstract: In city development of economy and structre bring traffic and carrying capacity of vehicle on increasingly. The reinforced concrete beam of the YaAn Bridge couldn’t bear actual load. In order to improve bearing capacity of the YaAn Bridge,augment the steel ratio of the reinforced concrete beam. In this paper ,the project design for repairing and strengthening of the reinforced concrete beam is introduced

Key words: the reinforced concrete beam, strengthen, bearing capacity

摘要： 由于经济和城市建设的发展，交通流量和车辆载重量增大，雅安大桥钢筋砼主梁承载能力不能满足使用荷载要求。应用增配主筋加固法，使桥梁承载能力提高。介绍其钢筋砼主粱加固设计方案
