Abstract
Out of the various seismic hazards, soil liquefaction is a major cause of both losses of life and damage to infrastructures and lifeline systems. For establishment of various important structures, suitable identification, evaluation and analysis of the liquefaction should be done in soil sites. Present scope of work is evaluation of liquefaction based on SPT data of a site. Liquefaction potential for a soil site was evaluated using empirical as well as analytical method for available data of 38 bore holes. Under analytical method, non-linear and equivalent linear ground response analysis of site was carried out using DEEPSOIL for near field and far field ground motion for same PGA value. The results were compared, and it was found that FOS against liquefaction potential by equivalent linear ground motion is less compare to non-linear ground motion, and FOS for near field earthquake ground motion is less compare to far field earthquake ground motion for same PGA value. Bore holes, which is susceptible to liquefaction, are located nearby to each other. It justifies the applicability of different methods and importance of confirmation of results.
