摘要
多肋多节段钢拱桥吊装施工,扣锚索众多,利用有限元程序对不同的拆索顺序进行模拟分析比较,确定出了合理的拆索方案,使得成拱后的线形更加逼近设计线形,为今后类似工程的拆索提供参考。
There are many buckle anchors in the multi-ribbed steel arch bridge multi-segmental construction,through the analysis and comparison of finite element program on a different order of demolition cord simulation analysis,a reasonable program of demolition cord is identified making the arch design as close as linear after the alignment which provide the reference for demolition cable in the future similar projects.
