COEFFICENT OF SECONDARY COMPRESSION

THE MECHANISM OF SECONDARY COMPRESSION IN SOILS CAN BE DESCRIBED IN TERMS OF CHANGES IN SOIL STRUCTURE. INSTANT AND DEALYED COMPRESSION ARE PARTS OF A CONTINUOUS PROCESS OF VOLUME CHANGE, AND FOR NORMALLY CONSOLIDATED NATURAL SOILS, THE COEFFICIENT OF SECONDARY COMPRESSION AND COMPRESSION INDEX CORRELATE WITH EACH OTHER. THE COMPOSITION AND PHYSICO-CHEMICAL- ENVIRONMENT DETERMINE THE COMPRESSIBILITY OF THE SOIL. FOR ANY GIVEN SOIL THE DELAYED OR SECONDARY COMPRESSION IS INFLUENCED BY SUCH FACTORS AS TIME, CONSOLIDATION PRESSURE, PRECOMPRESSION, SUSTAINED LOADING, REMOLDING, SHEAR STRESSES, RATE OF INCREASE IN EFFECTIVE STRESS, SAMPLE THICKNESS, AND TEMPERATURE. OF ALL THE FACTORS CONSIDERED, PRECOMPRESSION AND SUSTAINED LOADING HAVE THE MOST IMPORTANT INFLUENCE ON THE COEFFICIENT OF SECONDARY COMPRESSION. /ASCE/
