EFFECT OF RELATIVE DENSITY ON THE LIQUEFACTION SUSCEPTIBILITY OF A FINE SAND UNDER CONTROLLED-STRESS LOADING

THIS INVESTIGATION WAS AN EXAMINATION OF FACTORS AFFECTING THE LIQUEFACTION SUSCEPTIBILITY OF A REPRESENTATIVE POINT BAR SAND FROM THE MISSISSIPPI RIVER.ANISOTROPICALLY CONSOLIDATED TRIAXIAL SPECIMENS WERE SHEARED UNDER UNDRAINED CONDITIONS BY CONTROLLED-STRESS LOADING UNDER EFFECTIVE CONFINING PRESSURES RANGING FROM 1.0 TO 9.0 KG/SQ CM. THREE DISTINCT STRESS-STRAIN BEHAVIOURS, DESIGNATED AS LIQUEFACTION, LIMITED LIQUEFACTION, AND DILATION WERE OBSERVED.THE TEST RESULTS DISCLOSED THAT A LIMITING RELATIVE DENSITY EXISTS AT WHICH A LIQUEFACTION OR LIMITED LIQUEFACTION WOULD OCCUR FOR A SPECIFIED EFFECTIVE CONFINING PRESSURE. AS THE MAGNITUDE OF THE EFFECTIVE CONFINING PRESSURE INCREASED, THE RELATIVE DENSITY OF SPECIMENS WHICH LIQUEFIED ALSO INCREASED. THESE FINDINGS PERMIT AN ASSESSMENT OF LIQUEFACTION SUSCEPTIBILITY OF A SAND AT A GIVEN DENSITY AND CONFINING PRESSURE. A CRITICAL VOID RATIO CURVE WAS FITTED TO THE TEST RESULTS IN WHICH LIQUEFACTION OCCURRED. A BRIEF DISCUSSION IS INCLUDED ON THE EFFECTS OF RELATIVE DENSITY DETERMINATIONS BY VARIOUS LABORATORY METHODS. /AUTHOR/
