Evaluation of Liquefaction Potential of Pumiceous Deposits Through Field Testing

Abstract

Pumice materials are frequently encountered in many engineering projects in New Zealand. Because of their lightweight, highly crushable and compressible nature, they are problematic from an engineering and construction viewpoint. However, there is very little information on the liquefaction characteristics of pumice deposits and most empirical procedures available for evaluating the liquefaction potential of sands are derived from hard-grained (quartz) sands.
