Abstract

This paper presents the results of a series of experiments conducted on a PC wall-piles barrier. That barrier was built alongside a road passing through some sensitive sites, to assess its effectiveness in isolating vibration caused by running trains and dropping a weight. Then the effectiveness of PC wall-piles for controlling ground vibrations is discussed. Field measurements were performed for 5 cases having different types of PC wall-piles. The simultaneous measurement of vibration was performed at several selected points on the ground. Finally, a method for estimation of vibration reduction by PC wall-piles was developed, being based on wave penetration theory. The major findings from this series of experiments are as follows: 1. Vibration level as registered on the off-side of the PC wall-pile harrier was found to be 5 to 7 dB lower than that recorded at the site with no such barrier. 2. The maximum isolation effectiveness was obtained in the case of hollow PC wall-piles. 3. The theoretical results using the wave penetration theory showed a good agreement comparing with the field tests.

Ground Vibrations Isolation by PC Wall-piles
