Probable Depth of Liquefaction in Rangpur City Corporation Area

This paper represents a primary approach to determine the possible depth of liquefaction hazard in Rangpur City Corporation area. It was suspected that the investigated area of Rangpur have high liquefaction potential because from the lithological data it was observed that the foundation soil consists of loose sandy silt with a very shallow aquifer. Lithological data from various borehole was examined and probability of Liquefaction for every borehole are derived totally based on the probability analysis. From that it is found that liquefaction probability can reach values 30% to 50% at depth from 10m to 12 m in average. By keeping this depth under consideration while designing can reduce the amount of damage of human life and infrastructure.
