    Abstract: The geotechnical characteristics of the soil layers are one of the main factors influencing liquefaction potential of the ground. In common usage, liquefaction refers to the loss of strength in saturated, cohesionless soils due to the build-up of pore water pressures during dynamic loading. The following five screening criteria, are recommended for... Show More
