Evaluation of Soil Liquefaction (Case Study: Sanandaj City)

Liquefaction is the process by which soil pore water pressure thus increasing the solid state tothe liquid state turns while maintaining its original density. If the soil is saturated loose sandunder dynamic loads like earthquakes are, may Mvzlaty create an instance of thephenomenon of liquefaction is very important. During the earthquake, at a time more verticaleffective stress and pore pressure of the sand is like a fluid. The effects of soil liquefactionmay plunge the instruments on the ground or be tilted, buried style instruments such as pipescome up; damage to coastal structures, wells are filled. In order to reduce the damage causedby liquefaction during earthquakes, soil liquefaction can be consolidated and upgraded.Methods of soil improvement sand against liquefaction include: replacement of soil prone toliquefaction or soil, compacted soil in place using dynamic compaction and compression orinjection seismology and use of drainage sand and stone.
