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 liquefaction is generally diverse and extensive. Real time identification of liquefied sites is thus the foremost step in the study of soil liquefaction 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 usually characterised with the help of amplitude, frequency and duration parameters. The authors of this paper intend to investigate the role of dynamic soil properties in Liquefaction Potential (LP) assessment. This technical note thus presents an elementary approach to evaluate LP based on dynamic response of soils.
