既有桥嵌入式轨道系统优化设计

Optimal Design of Embedded Track System of Existing Bridge

嵌入式轨道具有适用性强、维修量小、减振降噪性能好等诸多优点,广泛应用于有轨电车项目建设。论文针对某地有轨电车项目跨越既有桥段嵌入式轨道纵向伸缩力进行理论分析研究,探寻轨-嵌入式道床-桥的相互作用力和变形分布规律,并提出优化建议。

Embedded track has many advantages,such as strong applicability,small maintenance,good vibration and noise reduction performance,and is widely used in tram project construction.This paper conducts theoretical analysis and research on the longitudinal expansion and contraction force of embedded track of a tram project crossing an existing bridge section,explores the interaction force and deformation distribution law of track embedded ballast bed bridge,and puts forward optimization suggestions.
