| 摘 要： | 采用高灵敏度加速度传感器,对北京东单-建国门区间的运营地铁进行了现场测试,为研究相似区段特殊的减振措施提供依据.测试结果的分析主要是针对振动敏感仪器的,在频域内采用1/3倍频程频谱,重点考虑低频段的地面响应.通过对测试结果的分析,得出了环境背景振动、公交车等地面车辆和地铁的地面振动响应规律.

| Abstract: | In-situ metro-induced ground vibration tests have been performed between Dongdan and Jianguomen interval in Beijing by using high sensitive acceleration sensors,so as to study vibration mitigation measures in other similar areas in Beijing.Test results are analyzed in one third octave band spectrums mainly regarding vibration-sensitive instruments and emphasizing on low frequency band.Ground vibration response laws are obtained in environment background vibrations,ground traffic and metro train. |
