摘　　要：地铁轨道振动对周边环境产生负面影响,为减缓轨道振动影响,某城市地铁建设工程隧道段采用了一种钢弹簧浮置板轨道以削弱其振动影响。为评价其减振效果,在铺设了浮置板轨道段和普通轨道段的隧道测试地铁线车辆在四种工况下引起的隧道壁振动加速度和轨道位移值,论文对浮板轨道及普通轨道在减振特性及减振效果上的差异进行了比较分析。通过实验结果分析得出采用评价模式对城市新建地铁隧道选择轨道形式及减振效果评价具有参考意义。The vibration of subway tracks has a negative impact on the surrounding environment.In order to mitigate the impact of track vibration,a steel spring floating plate track was used in the tunnel section of a certain urban subway construction project to weaken its vibration impact.To evaluate its vibration reduction effect,the acceleration and displacement values of tunnel wall vibration caused by subway line vehicles under four working conditions were tested in tunnels with floating plate track sections and ordinary track sections,and a comparative analysis was conducted on the differences in vibration reduction characteristics and effects between floating track and ordinary track.The test results and the evaluation model adopted are of reference significance for the selection of track type and the evaluation of vibration reduction effect of new urban subway tunnel.
