Experimental Evaluation of Vibration Effects Induced by Planed Railway Line on Surrounding Historic Tower
Using field experiments, the vibration effects of historic tower induced by planed railway line are estimated. The vibrations include the construction vibration and the traffic-induced vibration. The results show that the blasting construction leads to the significant increase in vertical velocity and acceleration. There is no difference between the background vibration of field and foundation of tower. Different types of the sites soil around the tower cause little change. Each measurement time showed an upward trend of vibration level with the increase of frequency. The closer the tower is to the vibration source, the larger the structural vibrations would be. The dominant frequency range for highway-induced vibration is 10-20 Hz. For train-induced vibration, the dominant frequency range is more than 40 Hz. Surface waves will result in amplification phenomenon of vibration velocity of ancient structures within a certain range.
