According to the finite element analysis of double-amplitude single-box and single room continuous stiff bridge,the paper concludes the self-vibration features of the corrugated steel web continuous stiff bridge,establishes respective PC continuous stiff bridge by referring to the load-ing capacity and undertakes the comparison of the finite element model,analyzes the influence of the bridge self-vibration features including the pile soil effect,pier column beam,and geometric shapes of the corrugated steel web,and achieves some conclusions.%通过对某双幅单箱单室波形钢腹板连续刚构桥进行有限元分析，得出该波形钢腹板连续刚构桥的自振特性，并依据承载能力等效原则，建立了相应的 PC 连续刚构桥有限元模型进行对比，分析了桩土效应、墩柱系梁及波形钢腹板几何形状参数等因素对桥梁自振特性的影响，得出了一些有价值的结论。
