摘要:
为了研究地铁隧道内浮置板轨道的实际减振效果，以我国某地铁线路的隧道段为研究对象，测试了普通道床轨道、重量级和中量级浮置板轨道产生的振动响应，分别在时域和频域内对各种轨道的振动特性进行对比分析，并采用Z振级进行综合评价，结果表明：轨道板和隧道壁的主要响应频段在80 Hz附近；重量级和中量级钢弹簧浮置板道床振动响应有5.3 dB的差异；各减振断面的隧道壁振动均满足相关规范的要求。
Abstracts:
In order to study the actual vibration reduction effect of floating slab track in metro tunnel, a tunnel section on metro line in China is taken as the research objective. The vibration responses of ordinary track bed, heavyweight and medium-sized floating slab track are tested within a certain domain of time and frequency, the vibration characteristics of various tracks are compared and analyzed, and the Z vibration level is adopted for a comprehensive evaluation. The results show that the main response frequency bands of track slab and tunnel wall are near 80 Hz; the vibration response of floating slab bed of heavyweight and medium-weight has a 5.3 dB difference, the vibration of tunnel wall of each vibration reduction section could meet the requirements of relevant codes.
