Liquefaction Potential of Sub-Surficial Soil Based on GRA of Smart City Jalandhar

Abstract

Liquefaction and related phenomenon have been in charge of enormous measures of harm in recorded seismic tremor all over the world. The city Jalandhar is under zone IV. It sustains the vulnerability of city to seismic forces. A number of multistoried high-rise buildings are under progress and several high-rise buildings are proposed for next few years. From the study of past earthquakes, we have demonstrated that liquefaction-induced ground failure may pose catastrophic damage threats to rural and urban infrastructure including buildings. To fulfill the safety purpose it is imperative that the new structure in Jalandhar be analyzed for seismic forces. To fulfill the need of the objective, the area was analyzed with the help of simplified procedure given by Seed and Idriss (1971) of liquefaction potential evolution is used. With the use of SPT result, ground response analysis has been done. Peak ground acceleration has been calculated using software. The estimated peak ground acceleration will be used to check liquefaction of specific sites in Jalandhar. The bore log data has been obtained from 10 locations of Jalandhar. From this analysis, it is obtained that there are only two sites which are likely to be effected under liquefaction.
