Model for predicting evolution of microstructural void ratio in compacted clayey soils

The hydromechanical behavior of compacted clayey soils is significantly influenced by its microstructure. microstructural void ratio a key parameter that strongly associated with the state. objective this study to provide practical and reliable estimation approach for predicting evolution clay subjected wetting drying paths. In paper, 12 was investigated quantitatively using mercury intrusion porosimetry (MIP) results. Based on study, comprehensive criterion has been developed identifying different pore populations interpreting MIP “as-compacted state line” proposed estimate initial at as-compacted An incremental linear constitutive model correlating “microstructural average skeleton stress” in following monotonic validated providing comparisons between predicted interpreted ratios all examined soils. can be extended modeling incorporating explicitly information.
