| Summary: | Pile driving operations are becoming a prevalent practice in Metro Manila due to the presence of soft soil conditions. However, ground vibrations are induced in the process, which could cause possible structural damages to the nearby existing structures. Ground vibration measurements were recorded at three designated sites at 3, 15, and 30 meters away from the pile-driving source through the use of three of Guralp's accelerometers. A defined attenuation behavior of the emitted vibrations was observed when the pile was in contact with the predominantly sand and silt layers, vibration prediction models for sand and silt layers were formulated and then validated with the measurements obtained at the other two sites, predicted results were correlated to existing vibration limits, a zone of influence was then generated and is capable of identifying the types of structures that are susceptible to structural damage within a radius of the source of pile driving. |
