地铁的运营对环境振动的影响已成为人们普遍关注的问题,振动波在土层中的传播规律是研究中的难点。介绍了毗邻地铁的某歌剧院场地地下土层振动现场实测,从速度振级角度分析了地铁轨道水平面土层中振动的水平和竖向的传播规律,并对车速、本底振动以及新型轨道减振措施等对场地振动的影响进行了阐述。
The impact of subway operation on environmental vibration has become a common concern, and the propagation of vibration wave in soil is a difficult point in the study. This paper introduces the measurement of the vibration of the underground soil layer of the opera house adjacent to the subway, and analyzes the horizontal and vertical propagation laws of the vibration in the soil layer of the subway track from the point of view of speed vibration. Vibration measures on the impact of site vibration were described.
