“…The elastoplastic soil models have been an essential cornerstone in the numerical analysis of geotechnical problems (Zhang et al 2020). Numerous elastoplastic soil models have been proposed to describe the complex mechanical behaviour of various soils under different load conditions (Dafalias 1980;Hashiguchi 1989;Gao et al 2014;Yao et al 2014;Liang et al 2019;Xiao & Desai 2019;Sun et al 2020;Gao & Diambra 2021). For instance, the Cam-clay model (Roscoe & Schofield 1963;Schofield & Wroth 1968) and the modified Cam-clay (MCC) model (Roscoe & Burland 1968) which are developed within the critical state soil mechanics framework have been widely used in analysing various geotechnical problems.…”

“…Six new parameters were introduced into the model compared to the parent MCC model [1]. Xiao et al [16] and Xiao et al [17] proposed a constitutive model for overconsolidated clays in the framework of disturbed state concept [18]. It is worth pointing out that a smaller number of parameters in a model provide a significant advantage by making the model simple for practical use.…”

Due to the influence of soil structure, structured soils exhibit significantly different mechanical behavior compared to the reconstituted soils having the same material. In this work, a theoretical analysis focusing on the mechanical behavior of structured soils is presented. Based on the mechanical behavior of the structured soil, a newly defined variable structural index was used as a measurement of the integrity of soil structure based on the concept of intrinsic compression line of intact structured soils. Furthermore, a novel correlation for the variation in volume of structured soils is established using effective stress and newly defined structural index as the constitutive variables. The novel correlation provided interpretation about the mechanism of compression behavior of the structured soils. Afterwards, the proposed correlation for the variation in volume was extended to triaxial stress state in the framework of subloading surface to include the effect of overconsolidation. Comparisons between the predictions and experimental results validated the proposed constitutive model for structured soils.
