ANALYSIS OF CIRCULAR FOOTINGS ON LAYERED SOILS

THE STRESS-DEFORMATION AND THE BEARING CAPACITY OF A CIRCULAR FOOTING RESTING ON AND BELOW THE SURFACE OF LAYERED COHESIVE SOLS ARE PERFORMED NUMERICALLY AND EXPERIMENTALLY. THE NUMERICAL RESULTS ARE OBTAINED BY EMPLOYING THE FINITE ELEMENT METHOD OF ANALYSIS. THE CONSTITUTIVE MODEL FOR THE SOIL BEHAVIOR IS DERIVED FROM THE NONLINEAR STRESS-STRAIN CURVES FROM TRIAXIAL TESTS UNDER VARIOUS CONFINING PRESSURES. THE NUMERICAL RESULTS ARE COMPARED WITH THOSE FROM MODEL PLATE-LOADING TESTS ON SINGLE AND TWO-LAYER COHESIVE SOIL SYSTEMS. THE BEARING CAPACITIES FROM THE FINITE ELEMENT ANALYSIS ARE ALSO COMPARED WITH THE COMPUTED VALUES ON THE BASIS OF CONVENTIONAL METHODS IN SOIL MECHANICS. GOOD AGREEMENT IS OBTAINED BETWEEN THE COMPARISONS. /ASCE/
