| Abstract: | A two-dimension dynamic finite element model is established to assess the vibration impact of vehicles on Line 8 of Beijing metro on adjacent sensitive buildings. Vibration velocity is taken as the control factor. The attenuation regulations of vibrations in low-rise and high-rise buildings are studied. The effect of foundation forms on vibration responses is also analyzed. Results indicate that the vibration influence is kept within the control standards and that there is no need to take special mitigation measures. |
