RATIO C/P' IN RELATION TO LIQUID LIMIT AND PLASTICITY INDEX WITH SPECIAL REFERENCE TO SWEDISH CLAYS
THE RATIO C/P' HAS BEEN DETERMINED FOR DIFFERENT TYPES OF SWEDISH QUATERNARY, SEDIMENTARY CLAYS, NORMALLY CONSOLIDATED OR NEARLY NORMALLY CONSOLIDATED. THE UNDRAINED SHEAR STRENGTH, C, HAS BEEN DETERMINED BY THE FIELD VANE. THE PRECONSOLIDATION PRESSURE P', HAS BEEN TAKEN AS THE EFFECTIVE OVERBURDEN PRESSURE AND, IN ADDITION, HAS BEEN DETERMINED BY OEDOMETER TESTS. THE C/P' RATIO HAS BEEN RELATED TO THE PLASTICITY INDEX, IP, AND COMPARISONS HAVE BEEN MADE WITH THE RELATIONSHIP ACCORDING TO SKEMPTON. C/P' RATIO HAS ALSO BEEN RELATED TO THE LIQUID LIMIT, AND COMPARISONS HAVE BEEN MADE WITH THE RELATIONSHIP ACCORDING TO HANSBO. THE SCATTERING OF THE TEST RESULTS AND THE DEVIATION FROM SKEMPTON'S AND HANSBO'S CURVES ARE GREAT, ESPECIALLY FOR QUICK CLAYS. THE INFLUENCING FACTORS AND DIFFICULTIES IN EVALUATING THE TWO PARAMETERS C AND P' ARE DISCUSSED. /A/RRL/
