Strain-based assessment of liquefaction and seismic settlement of saturated sand

This study presents results from an extensive experimental research on saturated clean sand deposits subjected to seismic loading. A total of 29 freshly reconstituted soil samples were tested under laboratory conditions. Strain-controlled, undrained, cyclic triaxial tests were conducted to evaluate...
