对地铁列车引起与地铁合建建筑结构环境振动响应进行现场测试,从时域和频域角度分析地铁列车引起合建建筑结构环境振动特性。分析地铁列车引起地铁合建建筑结构环境振动传播规律及频率分布特点,结合振动控制标准对环境振动进行了评价。研究结果表明,在地铁列车荷载作用下,合建建筑结构的振动幅值随距振源距离增大而减小;合建建筑结构上部结构的振动频率分布特性基本上与地铁线路结构一致,主要集中在20~80 Hz范围内;合建建筑结构横向环境振动水平比垂向环境振动小,振动响应幅值约为垂向的0.8倍,但两者处于同一水平,甚至在部分频率范围内比垂向速度振动水平高。

英文摘要：

Through in-situ experiments and analysis of metro-induced vibration characteristics of the jointly- built structure of subway and the buildings, this paper analyzed the characteristics of the vibration of building structures caused by the subway train from the perspective of the time domain and frequency domain. Further, analysis was performed on the regularity of wave propagation and frequency distribution, followed by the evaluation of the environmental vibration in combination of vibration control standard. The research findings showed that under the subway train load, the jointly-built structure vibration amplitude decreased with increasing distance from the vibration source. The vibration frequency distribution characteristics of the upper structure of the jointly-built structure were basically consistent with those of the structure of the subway line, with vibration frequency distribution being mainly concentrated in the range from 20-80 HZ. The horizontal environ- mental vibration level of the jointly-built structure was lower than the vertical one, while the transverse vibration response amplitude was about 0.8 times of the vertical vibration response amplitude. Although they were in the same range, the transverse vibration level was higher than the vertical vibration speed level even in certain frequency range.
