MECHANICAL IMPROVEMENT OF SOILS BELOW GROUND SURFACE

MECHANICAL IMPROVEMENT OF SOILS BELOW GROUND SURFACE MAY BE ACHIEVED BY DEEP COMPACTION OF COHESIONLESS GROUND, OR BY MODIFICATION OF COHESIVE SOILS BY THEIR PARTIAL REPLACEMENT WITH STRONGER MATERIALS INTRODUCED BY MECHANICAL MEANS. VIBRO-COMPACTION AND VIBRO-REPACEMENT USING A LARGE POKER VIBRATOR ARE DISCUSSED. THE ESSENTIAL PROPERTIES OF THIS MACHINE ARE DESCRIBED TOGETHER WITH ITS MODE OF USE, WITH OR WITHOUT JETTING FLUIDS. THE PROPERTIES OF TREATED GROUND WHICH DEPEND ON THE MACHINE, TECHNIQUE AND SOIL TYPE ARE INDICATED WITH EXAMPLES. THE PHILOSOPHY OF DESIGN OF TREATMENT IS DISCUSSED FOR STRUCTURES ON NATURAL SOILS OF COHESIONLESS, COHESIVE AND MIXED STRATIFIED TYPES, AD ON HETEROGENEOUS FILLS. EXAMPLES ARE QUOTED OF SETTLEMENTS OF FULL-SCALE STRUCTURES AND TEST LOADS, AND OF OTHER PERFORMANCE DATA. /RRL(A)/
