Obtained in a vibration test on a road section along a subway in Shanghai
the horizontal and vertical accelerations on test lines and at test points are presented in this paper.They have been changed to vibration grades
compared with the national standard
and analyzed the composition of vibration frequencies.The accelerations induced by trains in opposite ways were compared to analyze the regularity of vibration attenuation.The result can provide a reference for the isolation and reduction of vibrations in buildings and the planning and designing of urban rails.
