摘　　要：基于有限元分析软件ANSYS,对临河黄河特大桥超长联连续梁零号块进行了实体分析,得到了3种不同工况下的应力分布情况和受力特征,并为设计提供了依据和合理化建议。计算表明:按照现有设计,零号块在3种最不利工况下,应力状态良好,满足规范要求。Based on the finite element analysis software- ANSYS,we did the solid analysis about the zero block of the yellow river bridge in linhe which is a overlength units of continuous girder and obtained the distribution and characteristics of the stress. Based the result,we provided the basis and the rationalization proposal for design work. The analysis shew that the zero block was at a good stress state and the result met the requirements of standard under the three different conditions.
