预应力混凝土连续刚构桥的0号块箱梁段由于其构造及受力及其复杂，因此保证其安全十分重要。结合某连续刚构桥，使用 MIDAS ／FEA 软件建立0号块局部有限元模型，从整体模型中提取结构内力作为局部模型的边界条件，对其在施工、成桥及运营阶段等荷载工况下进行了应力分析，分析结果表明，该桥墩0号块受力均满足规范要求，计算结果已为该桥设计提供依据。

Due to the complex structure and stress state of segment NO.0 for the prestressed con-crete continued rigid frame bridge,it is important to make sure the quality and security of it.Based on one calculation example,the partial finite element model of segment NO.0 is carried out to calculate the stress of it when it is under construction,completed and service stage by using anslysis software MIDAS /FEA.Meanwhile the internal forces of the overall model is given as the boundary conditions for the partial model.The results show that the stress of segment NO.0 are in good agreement with the current codes and the results have been used for the design of the bridge.
