The recent advent of larger and heavier vehicles capable of carrying heavier loads at faster speed has resulted not only in land transportation systems with a greater complexity but in a higher level of vibration bringing about a more severe environmental hazard to their neighborhoods. These sources generate relatively long wave lengths, and barriers are not effective unless they are installed to a relatively great depths. A new ground vibration isolation method is described, which uses PC wall-piles. PC wall-piles offer an advantage in that vibration barriers are easier to build to a greater depth. Because of this advantage, barriers made of PC wall-piles appear to provieda great potential to tame ground vibration in future applications. This paper presents the results of a series of experiments conducted on a PC wall-piles barrier. That barrier was built along side 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 viblations is discussed.
