基于有限元法的相关知识，利用ANSYS软件对某异形连续梁桥进行了实体有限元建模及静力分析，考虑了恒载、车辆活载和温度荷载等工况，探索了桥梁在单一工况及最不利工况组合下桥面板的应力分布情况，并与规范容许值进行了对比和抗裂验算，结果表明，桥面受力状况良好，部分区域出现宽度为0.08 mm的纵向裂缝，但最大裂缝宽度满足规范要求。

Based on the knowledge of FEM,3D Solid model of a special shaped continuous beam bridge was built using ANSYS considering the dead load,vehicle live load and temperature load conditions. Bridge deck stress distribution was explored under single operating condition and the most unfavorable conditions combination. Results were compared with the allowable values. Research shows that the bridge works in good condi-tion and longitudinal cracks,0. 08 mm in width,appeares at some parts of the bridge. The maximum crack width meet the specification requirements.
