In Situ Seismic Investigation of Liquefaction Potential of Soils,

Abstract

Liquefaction is a term used to describe a process involving the complete loss of shear strength of loose- to medium-dense sand deposits (or other non-cohesive soils) below the water table during the passage of large-amplitude earthquake waves. The existence of such processes in nature is well evidenced by surface observations at many earthquake sites throughout the world (see, for example, Kawasumi 1968, Seed et al. 1990, and CAEE 1995). A primary objective of liquefaction research is the development of indicators, derived from in situ geotechnical measurements, that provide accurate assessment of liquefaction potential of a cohensionless deposit in a given earthquake environment.
