Abstract
Lots of research work is being carried out in evaluating the liquefaction susceptibility. The main objectives of these studies are to identify the regions which are vulnerable to liquefaction. In the present study, an attempt has been made to predict the liquefaction susceptibility based on corrected SPT values required to prevent the liquefaction for given return periods. The evaluation of liquefaction susceptibility requires the calculation of two parameters, seismic loading and the soil resistance. In most of the studies, the seismic loading will be evaluated based on probabilistic methods and the evaluation of soil resistance will be done based on deterministic analysis. In the present study these parameters were evaluated based on the probabilistic methods. The contour curves showing the spatial variation of SPT values required to prevent the liquefaction for return periods of 475 and 2500 years are presented here. The liquefaction hazard curves, based on SPT values for some of the selected cities in the study area are also presented here.
