DEEPSOUNDING TEST RESULTS AND THE SETTLEMENT OF SPREAD FOOTINGS ON NORMALLY CONSOLIDATED SANDS

FOR SETTLEMENT ESTIMATIONS OF SPREAD FOOTINGS BASED ON DEEPSOUNDING TEST RESULTS ON SANDS IT HAS BEEN USUAL TO UTILIZE THE ANALYSIS PROPOSED BY BUISMAN WHICH EMPLOYS A CONSTANT OF COMPRESSIBILITY AND THE COMPRESSION EQUATION. THE FIRST PART OF THE PAPER DESCRIBES AN EXPERIMENTAL INVESTIGATION WHICH WAS CARRIED OUT TO COMPARE THE PENETRATION RESISTANCE AND THE COMPRESSIBILITY CHARACTERISTICS OF THREE SANDS. THE RESULTS DETERMINED A RELATIONSHIP BETWEEN CONE RESISTANCE AND COMPRESSIBILLTY WHICH WAS INDEPENDENT OF THE SAND GRADING, PARTICLE SIZE AND OVERBURDEN PRESSURE FOR NORMALLY CONSOLIDATED SANDS. IN THE SECOND PART OF THE PAPER THE EXPERIMENTAL RESULTS ARE DISCUSSED WITH RESPECT TO FIELD TESTING, IN SITU GROUND CONDITIONS AND THE SETTLEMENT OF FOOTINGS. ESTIMATED AND OBSERVED SETTLEMENTS ARE COMPARED FOR SEVERAL SITES FOR WHICH CONE RESISTANCE/DEPTH PROFILES ARE AVAILABLE. A GOOD AGREEMENT BETWEEN ESTIMATED AND OBSERVED SETTLEMENT WAS OBTAINED PROVIDED THAT A CORRECTION WAS MADE TO THE ESTIMATED SETTLEMENT VALUES TO ALLOW FOR THE PROPORTION OF THE ULTIMATE BEARING CAPACITY OF THE SOIL MOBILIZED AT THE BEARING PRESSURE IMPOSED BY THE FOUNDATION. /RRL/A/
