A Case Study of Soil Improvement Against Liquefaction By Using Jet grout Technique

In liquefaction, the strength of the soil decreases and, the ability of a soil deposit to support structurefoundations for buildings and bridges is reduced. One of the major factors of lifeline damage inearthquakes is ground failures caused by liquefaction ofloose, saturated cohesionless soils. Its effects aremost 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 buildingsduring the 1906 San Francisco,California, earthquake. Nowadays several ground improvement techniqueshave been widely used to reducing liquefaction hazards by improving the strength, density, and/ordrainage characteristics of the soil. This paper, present application of jet grouting technique as a mostcommonly ground improvement method that used to prevent liquefaction for the construction of newbuildings or other structures, in Izmir, Turkey as a case study.
