Thesis ; no. 761 A thesis submitted in partial fulfillment of the requirements for the Degree of Master of Engineering at the Asian Institute of Technology, Bangkok, Thailand . Thesis (M.Eng.) - Asian Institute of Technology, 1975 Field investigations in the Bangkok area were carried out to measure vibration intensities induced by pile driving in terms of peak particle velocities. Measurement locations included ground surface, subsurface and the adjacent buildings. The sites selected were located within the compounds of the Crown Seal Factory, north of Bangkok and the South Thermal Power Plant of EGAT, south of Bangkok. Vibrations were recorded for several distances from a pile being driven, and also for various depths of the pile tip. The results showed that depending on the distance from the source, maximum values of vibration occurred either when the pile tip was in the sand fill layer on the surface, or penetrated the stiff clay stratum. Peak amplitudes of particle velocity were about inversely proportional to al.SO when the pile tip passed through the surface fill layer, and to d for all other strata below the surface layer. d represents the horizontal distance to the pile axis. Subsurface measurements carried out in boreholes showed a rapid decrease of vibration amplitude with depth. Most records were obtained for the vertical component of vibration. Measurements of the radial and tangential component were used for estimating the contribution of these components expressed as a percentage of vertical vibration. The maximum vibrations measured in the adjacent buildings were compared with damage criteria established by earlier investigators. It was found that the measured vibrations of structural elements were quite low. However, at the Crown Seal Factory site, pre-existing cracks near the window frame of a wall panel enlarged as a result of pile driving. No damage was noticeable at the EGAT site. It was found that the cone resistance obtained from Dutch Cone sounding tests could be employed to predict ground surface vibration. For the pile tip penetrating through clay or sand beneath the surface zone, the maximum particle velocity can be predicted from the equation where vmax = 0.0312 qc 0.3 E_d vmax = Particle velocity, mm/sec E = Energy, joules d = Horizontal distance, m qc = Cone resistance, kN/m2 If the pile tip penetrates a fill on the surface this equation may underestimate vmax{u2022} Piling (Civil engineering) Vibration Brenner, R.P., Chairperson Brand, E.W., Examination Committee Richardson, A.M., Examination Committee Australian Government, Scholarship Donor Asian Institute of Technology.
