Probability of Liquefaction in Rangpur City Corporation Area

The work is a primary approach to grab attention on probability of liquefaction hazard in Rangpur City Corporation area. The investigated area of Rangpur was suspected to have high liquefaction potential since the foundation soil consists of loose sandy silt with a very shallow aquifer. Standard Penetration Test (SPT), which follows the general format of the Seed-Idriss simplified procedure for evaluating liquefaction resistance of soils, is the method followed for this research. Probability Maps of Liquefaction with narrative summaries are constructed on the basis of analysis result. It is found that liquefaction probability can reach values 30% to 50% at some sites. This information can be helpful for making decision to construct risk-based design in this region.
