摘要:
对南昌西站综合交通枢纽进行模型仿真，从时域和 频域的角度分析南昌地铁 4 号线对该站的振动影响。 研究南 昌地铁 4 号线在不同行驶速度、不同隧道埋深下的振动传播 规律及频率分布特点。 研究结果表明，在地铁列车荷载作用 下，南昌西站的振动幅值随着振源距离增大而减小，在地面 距离轨道中心线 24 ~ 36 m、60 ~ 72 m 的区域出现振动放大 区。 车站不同结构层的振动频率分布特性基本一致，主要集 中在 0 ~ 60 Ｈｚ 范围内。 车站结构横向环境振动水平比竖向 环境振动小，竖向振动响应与横向、纵向的振动响应频域分 布较为一致。 车站结构关键点出现最大振级的频率随着结构 高度的增大逐渐向低频移动。
Abstracts:
Through a simulation of the large＿scale integrated transportation hub＿Nanchang West Railway Station，the vibra＿ tion impact of metro Line 4 on the integrated hub station is an＿ alyzed from the time domain and the frequency domain，and the vibration propagation law and frequency distribution char＿ acteristics of Line 4 under different running speeds and tunnel depths are studied. The results show that the vibration ampli＿ tude of the integrated hub station decreases with the increase of vibration source distance under the load of metro train， and the vibration amplification area is located in the range between 24 ~ 36 m and 60 ~ 72 m away from the center line. The vi＿ bration frequency distribution characteristics of different struc＿ tural layers are basically the same，which are mainly concen＿ trated in the range of 0 ~ 60 Hz. The horizontal vibration level of the station structure is smaller than the vertical environment vibration，and the vertical vibration response is more consistent with the lateral and longitudinal vibration responses. The fre＿ quency of maximum vibration level at the key points of station structure gradually moves to the lower frequencies as the height of the structure increases.
