CONTROL AND PERFORMANCE DURING CONSTRUCTION OF A HIGHWAY EMBANKMENT ON WEAK SOILS

METHODS OF CONTROLLING EMBANKMENT CONSTRUCTION OVER COMPRESSIBLE AND WEAK FOUNDATIONS TO ENSURE SAFETY AGAINST SHEAR FAILURE ALONG A CIRCULAR ARC ARE DESCRIBED IN THIS PAPER. THE DESIGN AND CONSTRUCTION PERFORMANCE OF A HIGHWAY EMBANKMENT CONSTRUCTED IN REVERE, MASSACHUSETTS, ON INTERSTATE 95 BY THE MASSACHUSETTS DEPARTMENT OF PUBLIC WORKS OVER DEEP COMPRESSIBLE DEPOSITS OF BOSTON CLAY ARE DESCRIBED, WITH EMPHASIS ON THE METHODS OF CONSTRUCTION CONTROL USED TO ENSURE STABILITY AGAINST CIRCULAR SHEAR-TYPE FAILURES DURING CONSTRUCTION. THE USE OF A RECENTLY DEVELOPED ICES COMPUTER PROGRAM TO COMPILE CONSTRUCTION CONTROL CHARTS BASED ON EFFECTIVE STRESS STABILITY ANALYSES, WHICH RELATE THE FACTOR OF SAFETY TO THE MEASURED PORE PRESSURES, IS PRESENTED, AND ASSESSMENT IS MADE OF ITS VALUE. DETAILED RESULTS OF SITE MEASUREMENTS OF EXCESS PORE PRESSURE, SETTLEMENT, AND HORIZONTAL DEFORMATIONS ARE PRESENTED TO INDICATE THE MAGNITUDE AND VALUE OF THESE MEASUREMENTS IN CONTROLLING THE RATE OF CONSTRUCTION AND IN DELINEATING AREAS IN WHICH REMEDIAL MEASURES ARE WARRANTED. A COMPARISON BETWEEN PREDICTED AND MEASURED EXCESS PORE PRESSURES IS MADE TO ASSESS THE APPLICABILITY OF SOME CURRENT THEORETICAL METHODS OF ANALYSIS IN PREDICTING STABILITY OF EMBANKMENTS BY THE EFFECTIVE STRESS METHOD. CONCLUSIONS ARE DRAWN ON THE APPLICABILITY OF THE EFFECTIVE STRESS METHOD OF STABILITY ANALYSIS USED IN CONJUNCTION WITH ON-SITE PORE PRESSURE MEASUREMENTS TO COMPILE FIELD CONTROL CHARTS FOR USE IN CONTROLLING THE RATE OF EMBANKMENT CONSTRUCTION. /AUTHOR/
