SCALE-DEPENDENT PLASTICITY ANALYSIS FOR SAND

NUMERICAL PROCEDURES FOR TWO DIMENSIONAL PLASTICITY ANALYSIS OF ZONAL FAILURE IN SAND HAVE BEEN MODIFIED TO INCLUDE THE CURVATURE OF THE MOHR-COULOMB ENVELOPE WITH PRESSURE. THE PROCEDURES ARE APPLIED TO PASSIVE RETAINING WALLS, SURFACE FOOTINGS AND DEEP STRIP FOOTINGS. THEY SHOW HOW THE ANGLE OF SHEARING RESISTANCE VARIES IN INDIVIDUAL FAILURE ZONES AND HOW ITS DISTRIBUTION CHANGES WITH SIZE OF STRUCTURE. IT IS CONCLUDED THAT FAILURE LOAD PARAMETERS SHOULD BE DIRECTLY RELATED TO STRUCTURE SIZE AND INITIAL SAND DENSITY.
