Abstract: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
   15~25Hz. 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.
