- Abstract
- Many researchers currently believe that liquefaction will not occur unless the peak ground surface accelerations generated at a site exceed some value between about 0.05g and 0.10g. The investigation attempted to determine the minimum levels of ground shaking capable of causing liquefaction both from seismic and non-seismic sources of vibration such as blasting, dynamic compaction, pile driving, construction equipment, and road and rail traffic. It now seems probable that levels of shaking significantly less than the value above are not only capable of causing liquefaction but have caused liquefaction in the past.
