摘　　要：采用Midas Civil有限元软件建立空间有限元模型,进行了系杆拱连续梁桥不同的虚拟横、纵梁间距对荷载横向分布影响的研究,并以齐齐哈尔北大桥为例,运用空间支反力法及杠杆法对该桥活载横向分布系数进行了计算,同时对其计算结果进行了对比分析,得出了一些有价值的结论,以供参考。The finite element software,Midas Civil,to illustrate the influence on the transverse load distribution caused by the intervals of differ-ent horizontal and vertical virtual beams of tied arch continuous girder bridge by establishing a dimensional finite element model. As Qiqihar north bridge for example,in order to calculate the transverse distribution coefficients of live load of this bridge,space support reaction method and lever method are applied,and the results are analysed. Some valuable conclusions are obtained,for reference.
