Abstract
Most of our understandin9 of the liquefaction phenomenon has come from laboratory tests. It would be desirable to express liquefaction resistance in terms of a parameter which can be measured both in the laboratory and in the field. It is proposed that the dilation angle or expansion rate of the sand is such a parameter. It is readily measured in the laboratory from drained simple shear or triaxial tests and in the field from self boring pressuremeter tests. Based on laboratory tests on Ottawa sand a chart is presented for estimating the liquefaction resistance of saturated sands in terms of dilation angle in addition to the usual parameters relative density and blow count. When the chart was used in conjunction with pressuremeter tests, a conservative estimate of liquefaction resistance of a hydraulic fill dam was obtained.
