Laboratory study on behaviour of static properties of saturated sand-gravel after liquefaction

By use of the medium scale dynamic triaxial apparatus(specimen size φ200 mm×510 mm),the laboratory tests on the sand-gravel after liquefaction were performed.The stress-strain responses and the main factors influencing the strength of liquefied sand-gravel were studied.It was shown that the strength of liquefied sand-gravel was mainly dependent on the confining pressure.
