Typical region closed to a station of Shanghai Metro Line 9was selected as research background in this article.The correlative data are collected based on the vibration test system of LabVIEW2010development platform.The response

characteristics and propagation law of vibration caused by train operation are analyzed based on the data collected from the three directions of the ground points corresponding to the metro tunnel central line as well as the vertical direction of the ground points with various distances from the central line.The result shows that the vertical vibration is the main form of ground vibration

and the vibration amplitude tends to decrease with the distance from the central line of the metro tunnel.There is an amplifier region at a distance of

15mfrom the central line.The sensitive frequency is in the range of 15

2

5Hz. The test area near the station of metro line 9has significant representativeness for the research on environmental vibration under the metro operation.No such research was reported on other metro lines.
