Abstract
Objective of this study is to compare the volumetric change of liquefied sand with that of dry sand under the same cyclic shear histories. To do this, multiple series of strain-controlled cyclic shear triaxial tests were conducted under both undrained and drained conditions. Under the same cyclic shear strain loading histories, the laboratory test results illustrated that the volumetric strain of drained cyclic test of dry sand was the same as that of post-cyclic drained test of saturated sand. The volumetric change under cyclic loading depends only on the strain histories and does not on the stress paths. In addition, it is found that the lower limit value of volumetric compression under cyclic shear can be noted. Under large shear exist, the void ratio converged at a particular value of the sandy material.
