Liquefaction Potential Assessment: An Elementary Approach

Liquefaction can be defined as a loss of strength and stiffness in soils.The damage caused by seismic soil liquefactionis generally diverse and extensive. Real time identification of liquefied sites is thus the foremost step in the study of soilliquefaction engineering, which can be achieved by analysing surface ground motion parameters and dynamic response of soil.The prediction of dynamic responses requires knowledge of dynamic soil properties whereas ground motion is usuallycharacterised with the help of amplitude, frequency and duration parameters. The authors of this paper intend to investigate therole of dynamic soil properties in Liquefaction Potential (LP) assessment. This technical note thus presents an elementaryapproach to evaluate LP based on dynamic response of soils.
