REPEATED LOAD MODEL FOR SUBGRADE SOILS: MODEL DEVELOPMENT

摘要: A load deformation model for subgrade soils is developed, where total cumulative axial strains are correlated with applied stresses and number of repetitions. The based on the results repeated tests a compacted silty clay. concept constant failure strain independent history presented used in proposed model. Results static triaxial tests, slow cyclic to verify that given compaction conditions confining pressure essentially stress history. Good agreement obtained between predicted experimental values from tests. Model predictions within plus or minus 10% results.
