摘　　要：为研究桥面板不同加载顺序对连拱桥受力性能的影响,本文以一座五跨空腹式连拱桥为依托,建立Midas Civil有限元模型,针对桥面板的不同加载顺序对拱桥主拱圈的影响进行模拟计算。对比分析后认为,从两端同时开始向中心对称加载的方式对连拱桥受力更为有利。In order to study the influence of different loading sequences of bridge panels on the mechanical properties of the continuous arch bridge,this paper uses Midas Civil to establish finite element models of a five-span vierendeel continuous arch bridge and analyze the influence of different loading sequence on arch ring of arch bridge.After comparative analysis,it is found that the symmetrical loading from both ends to the center is more advantageous to the mechanical behavior of the continuous arch bridge.
