| 摘 要： | 以京广线某特大桥为背景,对T型梁桥加固前后的力学性能进行分析研究。针对桥梁存在的问题,通过加强桥梁横向联系和加大桥墩截面尺寸的方式对桥梁进行加固,并建立加固前后的空间有限元模型,对桥梁加固前后的横向刚度和竖向刚度进行对比分析。

| Abstract: | Based on a T-shape beam bridge of the Beijing-Guangzhou line,a contrast analysis of the mechanical properties of the bridge is made after and before its reinforcement.The transverse connections were enhanced and cross-sectional areas were enlarged to solve the existing problems of the bridge.The 3-D FEA models were also established to analyze the lateral stiffness and vertical stiffness of the bridge before and after its reinforcement. |
