摘要:
为了研究水平地震作用下桥梁结构及地铁设施的相互影响,以山西省太原市解放路改造工程为依托工程,分别建立了高架桥、地铁站、高架桥及地铁设施组合结构的三维动力有限元模型,并考虑设置碎石隔震层,进行不同工况下结构的抗震性能分析。结果表明:由于碎石层的缓冲隔震作用,组合结构中高架桥的桥墩内力更小,且地震作用越大时,内力减小程度越大;另一方面,高架桥的建造对地铁结构的抗震性能影响较小。此外,对于桥梁结构而言,碎石层的厚度变化对桥墩内力有一定影响,但影响程度较小;而对于地铁结构而言,碎石层厚度越小,地铁柱剪力弯矩值往往会越大,但增加幅度有限。
Abstract:
Based on the reconstruction project of Jiefang Road in Taiyuan,the interaction between the bridge structures and subway facilities under the horizontal earthquake loads was investigated in this study.The three-dimensional finite element dynamic models,including the viaduct,subway station and the combined structure of the viaduct and subway facility,were performed,considering the gravel isolation layer.The seismic analyses of the structures were carried out.Due to the cushioning of the gravel layer,the internal forces of the piers of the viaduct under the combined structureswere lower than those under the single viaduct.When the earthquake action is greater,the reduction of internal forces will also be more significant.The viaduct has less influence on the subway structure.The variationin thickness of the gravel layer has a certain effect on the viaduct,but the influence is minor.When the thickness of the gravel layer becomes smaller,the shear force and bending moment of the subway columns tend to be greater,but the amount of the increase is limited.
