An overview on field and experimental evidences concerning seismic liquefaction induced settlement of buildings with shallow foundations

During earthquakes, loose saturated granular soils can experience a sharp rise in excess pore pressures and consequent strength loss as their structure attempts to compact, a phenomenon known as liquefaction. During and following liquefaction, soil pore fluid redistributes, causing the settlement of...

description During earthquakes, loose saturated granular soils can experience a sharp rise in excess pore pressures and consequent strength loss as their structure attempts to compact, a phenomenon known as liquefaction.
