Test results revealed that I_v was more suitable for depicting the compression behavior of pure clays than I_vH; whereas, for the compressibility of sand–clay mixtures, the normalized compression line by using I_v was obviously different from that of pure clays and traditional soils due to the presence of sand particles. Therefore, a four-phase analysis framework of sand–clay mixtures was introduced to unify the intrinsic compression behavior of soils with and without sands. It was found that the updated clay void index I_vc parameter was effective to unify the soil’s compression behavior by excluding the influence of sand particles in clays before the sand skeleton formation. After the formation of the sand skeleton, the cluster particles change the stress distribution of mixtures, leading to less stress being applied on the clay matrix and thus the bifurcation of the intrinsic compression behavior.]]> Sat 24 Mar 2018 08:43:42 AEDT ]]>
