摘　　要：为达到桥梁的拓宽、提载要求,拟采用钢筋混凝土套箍方式对某圬工拱桥进行加固,并通过MIDAS对圬工拱桥加固前后的内力进行分析可知,钢筋混凝土套箍承担了部分内力,提高了全桥的承载能力。For widening bridge and increasing load, a masonry arch bridge is proposed to be strengthened by a reinforced concrete hoop. According to the analysis of internal force by midas before strengthening and after strengthening, the reinforced concrete hoop share partial load from the old arch ring, and the full-bridge carrying capacity is improved.
