Abstract: In liquefaction, the strength of the soil decreases, and, the ability of a soil deposit to support structure foundations for buildings and bridges is reduced. One of the major factors of lifeline damage in earthquakes is ground failures caused by the liquefaction of loose, saturated cohesionless soils. Its effects are most commonly observed in low-lying areas near bodies of water such as rivers, lakes, bays, and oceans. For example, horizontal ground displacement damaged many pipelines, bridges, roads, and buildings during the 1906 San Francisco, California, earthquake. Nowadays several ground improvement techniques have been widely used to reduce liquefaction hazards by improving the strength, density, and/or drainage characteristics of the soil. This paper presents the application of the jet grouting technique as a most commonly ground improvement method that is used to prevent liquefaction for the construction of new buildings or other structures, in Izmir, Turkey as a case study.
