Abstract

To study environmental vibration problems caused by urban traffic, field test of ground vibration induced by the traffic load were carried out on a city road and attenuation of the vibration was analyzed from the time domain. Used MATLAB software to curve fitting attenuation coefficient to calculate the variation of vibration with depth. The vibration with depth was analyzed through the attenuation coefficient. The results show that the environmental vibration caused by road traffic load was mainly in vertical direction. In addition, environmental vibration in the transverse and vertical directions were both gradually decreasing with the increase of the distance from vibration source. Vibration attenuation was rapidly reduced within 10m and there was almost no vibration in 57 m.
