[摘要] 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。

Abstract: Environmental vibration effect due to urban metro train is paid more and more attention nowadays, and the propagation regulation of vibro-wave in soil is a key in this field. The vibration measurement of an opera house near to one metro train line was presented, the horizontal and vertical environment vibration transportation of vibration velocity were then analyzed, and some influence ingredients such as velocity oftrain ,background vibration and new measurement to reduce vibration of rail were expatiated.
Keywords: metro train; vibration; test; transportation
