This study focuses on the vibration effects of both metro (subway) tunnel construction and metro-operating traffic on existing buildings. To that end, a four-story reinforced concrete building located between two metro tunnels of Üsküdar–Ümraniye–Çekmeköy Metro Project (UUCMP) was monitored both during the tunneling stages of construction and after the metro traffic started. Acceleration records were gathered from the building during the pass of two tunnel boring machines (TBMs) just below the building. Both magnitudes of the acceleration and the building frequencies were investigated for the active and passive stages of TBMs. The operation of the first TBM caused an obvious increase in the magnitudes of the vibration measured from the building, while the operation of the second TBM did not show any meaningful increase in the vibration magnitudes. These data were evaluated together with the characteristics of the soil between the building and the metro tunnels. After the completion of the construction, the metro lines were put into service. In this stage, acceleration measurements were gathered to reveal the effects of metro traffic on the studied building as well. It was seen that the metro traffic increased the magnitude of the vibration on the building. Firstly, this study underlined the importance of the soil profile between the tunnels and the studied structures for the propagation of TBM-induced vibrations. Secondly, in both tunnels, daily metro traffic caused higher magnitudes of vibration on the studied building compared with those of the TBMs. In conclusion, TBM vibration data can be used for detecting and determining critical structures in order to take precautions during the construction stage before the metro lines are put into service.

调查地铁隧道在施工和运营过程中的动载荷对既有建筑物的影响

这项研究集中于地铁（地铁）隧道建设和地铁运营对既有建筑物的振动影响。为此，在施工的开挖阶段和地铁通行之后，对位于Üsküdar–Ümraniye–Çekmeköy地铁项目（UUCMP）的两条地铁隧道之间的四层钢筋混凝土建筑进行了监控。在建筑物下方的两台隧道掘进机（TBM）通过过程中，从建筑物收集了加速度记录。研究了TBM主动和被动阶段的加速度幅度和建筑物频率。第一个TBM的操作导致从建筑物测量的振动幅度明显增加，而第二个TBM的操作并未显示出振动幅度的任何有意义的增加。这些数据连同建筑物和地铁隧道之间的土壤特性一起进行了评估。施工完成后，地铁线路投入使用。在此阶段，收集了加速度测量值以揭示地铁交通对研究建筑物的影响。可以看出，地铁交通增加了建筑物的振动强度。首先，这项研究强调了隧道和研究结构之间的土壤剖面对于TBM引起的振动传播的重要性。其次，与隧道掘进机相比，两条隧道的每日地铁通行量都对被研究建筑物造成了更大的振动。结论，
