OPTIMUM DESIGN OF PRE-LOAD AND SAND DRAINS

THE TERZAGHI CONSOLIDATION THEORY IS USED TO FIND THE OPTIMUM DESIGN OF A COMBINED PRELOADING AND SAND DRAINS INSTALLATION TO CONSOLIDATE SOFT CLAY SOILS. THE VARIABLES INVOLVED ARE: AVAILABLE TIME, INTENSITY OF PRELOADING, SAND DRAINS SPACING, THICKNESS OF THE SOFT LAYER, HORIZONTAL-TO- VERTICAL PERMEABILITY RATIO, UNIT COSTS OF PRELOAD AND OF SAND DRAINS. A CLOSED-FORM ANALYTICAL SOLUTION HAS NOT BEEN OBTAINED; NUMERICAL SOLUTIONS OF SOME PARTICULAR CASES ARE REPORTED. THE RESULTS SHOW THAT A MINIMUM COST SOLUTION IS ALWAYS FOUND; IN SOME INSTANCES A SOLUTION SLIGHTLY DIFFERENT FROM THE OPTIMUM ON INVOLVES A MUCH HIGHER COST.
