Investigation on Ground Vibration Induced by Construction Traffic and Normal Traffic

Abstract

Abstract: With the development of infrastructure facilities all over the country, many construction activities are carried out causing the construction traffic increased. As a result of movement of heavy vehicles, people feel annoyances so that many complaints against this construction traffic have been arisen. Objective of this study is to investigate the characteristics of the ground vibrations induced by construction traffic and normal traffic. A road construction site and a road near to stone crusher were selected. Ground vibrations induced by five dump trucks and one vibrating roller at 1m away from the edge of the road were measured using the four channel seismograph. Ground vibration levels experienced during period of construction traffic were greater than that for normal traffic and dominant in vertical direction. When operating a dump truck, Peak Particle Velocity (PPV) of the ground vibration in the vertical direction was in the range of 0.127-1.400mm/s while transverse and longitudinal directions ranges were 0.079-0.730mm/s and 0.127-0.825mm/s, respectively. Maximum vibration range experienced was 2.70-4.16mm/s induced by vibrating roller in vertical direction. Their transverse direction and longitudinal directions vibrations levels ranged from 1.41 mm/s to 2.05mm/s and from 1.49 mm/s to 3.35 mm/s, respectively. Vibrations induced by passenger vehicles ranged from 0.079 mm/s to 0.143mm/s in all three directions. People may feel annoyances from construction traffic because the construction traffic moves continuously and induced greater PPV compared with normal traffic.
