A case study on silty sand liquefaction—2010 Hsin Hwa liquefaction in Taiwan

Abstract

Silty sand liquefaction has been of great interest of research in geotechnical earthquake engineering, especially for the silty sand containing a large amount of non-plastic fines. This article presents a case study on non-plastic silty sand liquefaction. A new sampling technique, Gel-Push sampler, that could retrieve undisturbed non-plastic silty sand and results of series dynamic triaxial tests those investigated influences of fines contents, void ratio, as well as sampling disturbance are reported. Research progress presented here is hoped to be helpful in understanding mechanism as well as consequences of non-plastic silty sand liquefaction.
