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.
