| 摘 要： | 以徐州和平路跨越铁路站场斜拉桥为背景，建立了空间板梁有限元模型进行动力特性分析，将分析结果与脊梁有限元模型计算结果和实桥测试结果进行了对比．研究结果表明：宽跨比较大桥梁采用板梁结合模型较脊梁模型更准确，对同类型桥梁设计有一定的借鉴作用．

| Abstract: | Taking peace cable-stayed bridge of Xuzhou as the background, spatial plate girder finite element model is established to study the dynamic characteristics of this bridge. Three kinds of results are compared for this bridge correspondingly by the plate girder model, backbone girder model and real bridge test. The results show that plate girder model is more accurate than backbone girder model to the bridge with big wide- span ratio,which plays a reference for design work of the same type bridge. |
