［摘要］對京滬高鐵徐州東站旅客人行天橋的振動及減振措施進(jìn)行研究。通過實測和計算結(jié)果對比分析，確定列車風(fēng)是引發(fā)天橋振動的主要因素，并進(jìn)一步對列車提速情況下的振動響應(yīng)進(jìn)行計算；為確保人行天橋的安全性和舒適性，提出了合理可行的減振方案，并對各種減振方案的效果進(jìn)行了計算分析。經(jīng)計算，人行天橋采用增設(shè)立柱和阻尼器方案后，主梁跨中區(qū)域和橋面跨中區(qū)域的減振效果最為明顯。

Abstract: The vibration and vibration reduction measures of passenger footbridge in Xuzhou East Station of Beijing-Shanghai high-speed railway were studied. Through comparative analysis of the measured and calculated results, train wind is the main factor to cause the vibration of passenger footbridge. The vibration response in the case of train speeding up was further calculated. To ensure the safety and human comfort level of the bridge, feasible vibration reduction measures were proposed and performance of measures was analyzed. Through calculations, the scheme of additional columns and dampers that the passenger footbridge adopted has obvious damping effects in midspan regions of main girder and footbridge.
Keywords: passenger footbridge in high-speed railway station; vibration; train wind; human comfort level; vibration reduction
