摘　　要：利民桥为5跨连续拱桥,以其落架施工为研究背景,采用刚度折减的方法进行有限元模拟分析,并对应力、变形进行监控。通过实测值与理论值的对比分析可以看出,文章采取的落架方案满足设计要求,对同类桥梁的施工具有参考意义。In the paper,the construction of scaffold demolition of Limin bridge,a continuous arch bridge with 5 spans,is used as research background and simulated by finite element ,stress and deformation monitor are also carried out . By comparing measured results with theoretical calculation results,the method adopted for scaffold demolition meets the design requirements and could provided references for the same bridges.
