| 摘 要： | 以府保黄河铁路桥桥梁健康状况评估为目标,通过使用ABAQUS工程模拟有限元软件,在建立连续梁模型的基础上,分别从桥梁自振频率、列车横向摇摆力作用下变形,以及动力下的桥梁竖向挠度、横向摇摆和应变-应力关系上进行桥梁状况模拟及分析,为工程技术人员在铁路桥梁结构分析上提供了有效的方法.

| Abstract: | To evaluate the health of FU-BAO railway bridge,based on the formulation of the continuous beams,the bridge natural frequency,deformation based on horizontal sway force,vertical deflection,and relationship between strain and stress were simulated and analyzed by ABAQUS FEA software.The result had some reference value to provide an effective method for the further research and designing. |
