| 摘 要： | 设计制作了波形钢腹板混凝土连续箱梁的试验梁，并建立有限元模型对其动力特性进行了计算和分析，同时对其动力特性进行了实测.试验梁的有限元分析结果与实测结果对比分析表明：两者差别较小，证明了实测结果的正确性.制定了在试验梁的不同位置减少横隔板的方案，不同方案的计算结果表明：支座横隔板对箱梁动力特性的影响最大，而中横隔板基本不...

| Abstract: | Through design and construction of the long test model of the prestressed concrete box girder with corrugated steel webs,the finite element models of the girder are established and the dynamic characteristics of the girder are calculated and analyzed.According to the dynamic characteristics of the tested girder,the experimental schemes are arranged and the dynamic characteristics of the girder are measured.The comparison between the measured results and the finite element analysis results show that there is... |
