EFFECT OF SOIL BLANKETS AND PRELOADING ON SETTLEMENT

EXCESSIVE SETTLEMENT MAY OCCUR IN COMPRESSIVE SOILS. FOUNDATION STRUCTURES OFTEN MAY BE PLACED ON COMPRESSIBLE MATERIAL TO WHICH SOIL BLANKETS AND NATURAL OR MANMADE PRELOADS HAVE BEEN APPLIED, MAKING DEEP FOUNDATIONS UNNECESSARY. CHARTS AND TABLES ARE INCLUDED FOR CALCULATING VERTICAL STRESSES AND SETTLEMENT OCCURRING UNDER PRELOADS OF DIFFERENT SHAPES. A METHOD FOR DESIGNING PRELOAD DURATION, RATHER THAN BASING DURATION ON AVERAGE CONSOLIDATION, IS PRESENTED.
