Abstract
Knowledge of the attenuation characteristics of truck-induced ground vibrations has gained importance for micro-vibration mitigation of high-tech facilities. This study conducted an in-situ experimental study on the attenuation characteristics of truck-induced ground vibrations. The ground vibrations were generated by the passage of a truck on a low-cost road with different weights and speeds. Eight low frequency, one component, 941B vibration sensors were fastened on the ground surface to record the vertical velocity time histories of ground vibrations at eight measurement points with different distances. The vibration level was evaluated in terms of the vertical maximum displacement obtained by integrating the measured velocity time histories. The vibration level represented by the vertical maximum displacement decayed monotonically but nonlinearly with distance from the road. Ground vibrations at the measurement points that were close to the road decayed more rapidly than that at the measurement points far away. In general, the maximum displacement of ground vibrations induced by the 30-ton truck at a measurement point was smaller than that of ground vibrations induced by the 18-ton truck with the same speed.
