地铁车站地面站厅层振动与噪声试验分析
|
摘要
为了分析和评价地铁车站列车运行产生的振动与噪声对站厅工作环境的影响,对某地铁站的地面站厅层的振动与噪声进行现场实测,在时域内分析振动与噪声特性,并将实测结果与我国环境振动与噪声标准进行对比和分析,对不满足标准的办公室进行减振降噪装饰处理。研究结果表明:当列车进出车站时,地面站厅结构竖向振动明显大于水平振动;实测的最大竖向振动加速度级为86.5~105.7 d B;站厅层楼板的振动明显大于其他位置处的振动;地面站厅内最大瞬时A声级为69.7~74.3 d B(A)。采取减振降噪措施后,办公室位置处的振动和噪声得到了较好改善。研究工作对类似工程的振动与噪声评价和减振降噪设计具有重要的参考价值。
In order to analyze and evaluate the influence of train-induced environment vibrations and noise of overground hall at subway station, field measurements of vibrations and noise of overground station hall at a subway station were carried out, and the characteristics of vibrations and noise were analyzed in the domains of time. Then, the results were compared with the national vibration and noise standards for the environmental impact assessment of vibration and noise, and the measures of vibration and noise reduction had been taken to decorate the offices which cannot meet the requirements. It is found that when trains pull into or leave the station, the vertical vibration of overground station hall structure is significantly larger than the horizontal vibration with a measured maximum vertical vibration acceleration level of 86.5~105.7 d B; the vibration of floor is significantly larger than other sites at station hall; and maximum A-weighted sound pressure level of overground station hall is in the range of 69.7~74.3 d B(A). The vibration and noise level of offices can be effectively improved by the proposed mitigation measures. The research results can provide reference for evaluation and reduction design of vibration and noise of similar engineering structures.
