Vibroflots – The reasons behind Vibroflotation
Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquakes shaking and/or other rapid loadings.
This and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world.
Normally occurs in saturated soils. That is, soils in which the space between individual particles is completely filled with water. This water exerts a pressure on the soil particles that influences how tightly the particles themselves are pressed together.
Prior to an earthquake, the water pressure is relatively low. However, earthquake shaking can cause the water pressure to increase to the point where the soil particles can readily move with respect to each other.
