BEHAVIOR OF SANDS UNDER SURFACE LOADS

COMPARISONS ARE MADE OF THE INSTRUMENTATION, SAND TYPES AND TECHNIQUES USED TO EXAMINE HOW THESE FACTORS INFLUENCE THEIR RESULTS. THESE RESULTS ARE ANALYZED TO REVEAL ANY GENERAL PATTERNS, OR LACK OF PATTERNS, IN THE BEHAVIOR OF UNIFORM SAND MASSES SUBJECT TO SURFACE LOADS AND TO EVALUATE THE USEFULNESS OF A SIMPLE ELASTIC THEORY IN PREDICTING THIS BEHAVIOR. IT WAS FOUND THAT VERTICAL DIRECT STRESSES AND RADIAL- VERTICAL SHEAR STRESSES ARE REASONABLY WELL PREDICTED BY THEORY, WHILE THE RADIAL AND TANGETIAL DIRECT STRESSES SHOW CONSIDERABLE DIFFERENCES BETWEEN THE THEORY AND THE VARIOUS SETS OF RESULTS. THE MEASURED MAXIMUM SURFACE DISPLACEMENTS, EXPRESSED AS RATIOS OF THE PRODUCT OF THE RESPECTIVE LOADING PRESSURE AND RADIUS, SHOWED EXTREMELY LARGE DIFFERENCES. THESE REFLECT THE INFLUENCE OF RELATIVE DENSITY, COMPACTION METHOD, AND PRELOADING. /AUTHOR/
