| 摘 要： | 采用SAP2000有限元软件建立某单拱面预应力混凝土系杆拱桥的动力分析计算模型,并对结构进行E1、E2水准地震作用下的反应谱分析,对拱肋、吊杆、支座等构件和桩基进行抗震性能校核,结果表明除支座在E2地震作用下发生剪切破坏外,其他构件均满足抗震性能要求。

| Abstract: | The dynamic analysis model of single arch bowsting prestressed concrete bridge is builded utilizing SAP2000 FEM software,and the 2-level response spectrum analysis and property verification are carried out,concluding that the aseismic capability of the arch rib,suspender,pile foundation meet the earthquake demands except the shear failure of bearings under E2 earthquake action.It aimes to provide reference for similar engineering. |
