THE PERFORMANCE OF THE FOUNDATION UNDER A HIGH EMBANKMENT

THE MAIN OBJECTIVE IS TO DEVELOP IMPROVE METHODS FOR PREDICTING THE DEFORMATION AND STABILITY OF HEAVY EMBANKMENTS PLACED OVER THICK DEPOSITS OF SOFT SOIL. THIS REPORT PRESENTS THE MEASURED PERFORMANCE OF THE "NE TEST EMBANKMENT," BUILT IN 1957 AS A RESEARCH EFFORT PRIOR TO INTERSTATE CONSTRUCTION IN THE AREA NORTH OF BOSTON. THE MOST IMPORTANT ASPECT OF THE MEASURED PERFORMANCE WAS THE LARGE DIFFERENCE IN SETTLEMENT AMONG THE THREE CLOSELY SPACED SETTLEMENT PLATFORMS. GENERALLY, THE DATA AVAILABLE FROM THE EXPLORATION AND FIELD TESTING PROGRAM WERE INSUFFICIENT TO EXPLAIN THIS BEHAVIOR. THE DIFFERENCES IN PERFORMANCES PREDICTED BY SEVERAL METHODS OF ANALYSIS, RANGING FROM SIMPLE TO VERY SOPHISTICATED, WERE SMALL COMPARED TO THE DIFFERENCES IN MEASURED PERFORMANCES. THE KEY TO IMPROVED PREDICTIONS IS MORE COMPLETE EXPLORATION DATA INCLUDING BOUNDARY CONDITIONS AND SOIL PROPERTIES.
