COMPRESSIBILITY AND STRENGTH OF STIFF INTACT CLAYS

RESEARCH ON THE MECHANICAL BEHAVIOR OF STIFF INTACT CLAYS BELONGING TO PLIO-PLEISTOCENIC MARINE FORMATIONS IS DESCRIBED. THE GENERAL FEATURES OF THE 19 DEPOSITS EXPLORED ARE SIMILAR AND THE LARGE VARIATIONS IN THE PRECONSOLIDATION LOAD AMONG THE DEPOSITS ALLOW THE INVESTIGATION TO COVER A RANGE OF MECHANICAL PROPERTIES UNUSUALLY WIDE IN THE STUDY OF NATURAL SOILS. THE VIRGIN CONSOLIDATION LINE OF THESE CLAYS IS STRAIGHT UP TO A PRESSURE AS HIGH AS 600 KG/SQUARE CM. THE COMPRESSION INDEX DEPENDS ON THE IN-SITU VOID RATIO, IRRESPECTIVE OF THE PLASTICITY OF THE SOIL; THIS CORRELATION IS INTERPRETED AS AN INDEX OF THE PREVAILING INFLUENCE OF THE STRUCTURE OF THE SOIL. THE SHAPE OF THE FAILURE ENVELOPE IN TERMS OF EFFECTIVE STRESS AND THE PORE PRESSURE RESPONSE ARE RELATED TO THE PRECONSOLIDATION LOAD DEDUCED BY CONSOLIDATION TESTS. /RRL/
