Coelho, PALF and Haigh, SK and Madabhushi, SPG and O'Brien, AS (2003) On the use of densification as a liquefaction resistance measure. BGA International Conference on Foundations, Innovations, Observations, Design and Practice. pp. 227-237.Full text not available from this repository.
The use of densification to improve the performance of shallow foundations during the centrifuge modeling of earthquake-induced liquefaction on level sand deposits is discussed. The densification of liquefiable ground provided protection against or significantly reduces liquefaction-related damage. Propagation of accelerations in the deposit exhibited considerable distinct features according to the relative density of the sand in the model. It was found that during the first couple of cycles, the dense soil amplifies the fundamental frequency component of the earthquake and preserves the higher frequency components.
