Liquefaction Of Soil: is the phenomenon in which the soil behaves like liquid means it losses its strength and stiffness due to intense shaking of an earth quake. ; How does liquefaction of soil occur [REASONS]: liquefaction of soil occurs in saturated soil in which water is entrapped in the pores means pores are filled with water. This water exert pressure of the particles of soil but in first this pressure is small but when earthquake occur the water pressure increases and hence due to this increase in pressure the strength  contact bond between the particles decreases. So by this way the soil strength decreases and the soil losses its ability to support load. Conditions for liquefaction of soil: Following are some conditions for liquefaction of soil: loose granular soil saturation of ground strong shaking Effects of liquifaction of soil: As we know due to liquefaction settlement occurs in soil and due to this settlement alot of prob...
