The Effectiveness of Pre-Cast Wall-Piles in Reducing Ground Vibration

This paper presents the results of a study of the effectiveness of pre-cast wall-piles for controlling ground vibrations. Field measurements have been performed for five cases of different types of pre-cast wall-piles. A method for estimation of vibration reduction by pre-cast wall-piles has been developed, based on wave penetration theory.

Vibration levels as registered on the off-side of the PC wall-piles barrier were 5 to 7 dB lower than that recorded at the site with no such barrier. Theoretical results, using the wave penetration theory showed good agreement with the field tests.
