摘　　要：对沈阳一座已建成的无梁板桥基于平面杆系分析方法和空间有限元分析方法进行验算,分别建立平面杆系模型、空间有限元模型,分析计算结果,得出在平面杆系分析和空间有限元分析下,无梁板桥承载能力及裂缝计算结果的差异以及设计注意事项。The check calculation on a beam -less slab bridge built in Shenyang is made basing on the analytical methods of plane frame system and space finite element. The models of plane frame system and space finite element are respectively made. Through analyzing the calculation result, we can obtain the difference between the bearing capacity of beam - less slab bridge and calculation result of crack under the analyses of plane frame system and space finite element as well as matters needing attention in design.
