Comparison of different methods for evaluating the liquefaction potential of sandy soils in Bandar Abbas

Liquefaction is a phenomenon in which the shear strength of the soil dramatically is reduced or even eliminated in a short time. This phenomenon occures in non-cohesive , saturation and sleazy soils that have been subjected to ground motions and as a result earthquake occurs. Different methods are presented for evaluating liquefaction potential such as Seed et al, NCEER workshop, regulations of china and so on. This study compared the results of different methods for evaluating liquefaction potential (at least four methods) in the sandy soils of Bandar Abbas coastal city. Based on this , the results of standard penetration test from geotechnical data of two boreholes drilling machine have been used in the coastal city of Bandar Abbas.
