摘　　要：通过对广州地铁一号线沿线地上 6 6个截面 ,地下 1 0个截面的振动测试 ,对不同的隧道截面形状给出不同的地表面振动传播公式 ,公式表明地面振动Z振级由振源振动、地质条件、列车运行速度。Vibration test was carried out at 66 points on the ground and 10 points under ground along the first line of Guangzhou Subway. A formula of vibration transportation of subway vibration with different channel cross section was given. It shows that Z direction environment vibration transportation is controlled by original vibration, soil condition, train velocity, curvature radius of rail line and distance from channel side wall, etc.
