以已建成的某波形钢腹板PC组合三跨（50m+80m+50m）连续箱梁桥为实例，按照该桥的运营情况，通过运用Midas/Civil软件的建模和有限元分析，检验和复核这种桥型结构在3种最不利效应组合（短期效应组合、标准值组合和承载能力极限状态基本组合）以及11种荷载工况下的抗弯、抗剪、抗裂、挠度以及腹板的强度的变化情况，结果表明其有限元模型在各种荷载工况组合下，结构能够很好的满足规范和设计文件的要求。

According to the example of the combination of three corrugated steel webs(50m+80m+50m) across PC continuous box girder bridgewhich has been built and used.According to the bridge after the completion of operations, through the use of built Midas/Civil Software finite element modeling and analysis to make inspection and review of this bridge type structure in a combination of the three most adverse effects (short-term effects of the combination, and the standard combination of values and ultimate limit state the basic combination), and 11 kinds of load cases of bending and shear , crack deflection and strength of the web can meet the requirements of the existing norms, and the results show that its finite element model under various load combination, and the structure can wel meet the requirements specification and design documents.
