“…In fact, in the past decades, time-dependency of the deformation property of saturated clay was widely reported in literatures (Leroueil et al, 1985;Crawford, 1986;Leroueil & Marques, 1996;Tatsuoka et al, 2002;Kim & Leroueil, 2001;Den Haan & Kamao, 2003;Imai et al, 2005;Tanaka et al, 2006;Watabe et al, 2008;Qu et al, 2010;Degago et al, 2011；Ye et al, 2014. Through conducting a small-scale physical model…”

“…On the other hand, because isotache concept can generally demonstrate the long-term consolidation behavior for Osaka Bay clay, even with a developed structure, as shown in Watabe et al (2008), the consolidation behavior generally results in hypothesis B. Particularly, if we deal with high-quality clay samples with a developed structure, hypothesis B is strongly supported.…”

“…These simulations in Figs. 18 describe well the strain rate eŠects in one-dimensional compression for over consolidated clay and structured clay reported in the literature (e.g., Leroueil et al, 1985;Tanaka et al, 2006;Watabe et al, 2008). Figure 19 shows the simulated results of the onedimensional compression behavior under constant strain rate tests including some stress relaxation periods on a structured soil.…”

A simple and uniˆed constitutive model for soils, considering various eŠects such as the in‰uences of density, bonding, time dependent behavior and others, is presented in this paper. The elastoplastic behavior of over consolidated non-structured soils under a one-dimensional stress condition isˆrstly presented by introducing a state variable that represents the in‰uence of density (stage I). To describe the one-dimensional stress-strain behavior of structured soils, attention is focused on density and bonding as the main factors that aŠect the response of this type of soil, because it can be considered that soil a skeleton structure which is in a looser state than that of a normally consolidated soil is formed by bonding eŠects (stage II). Furthermore, a simple method is presented which allows for other soil characteristics to be considered, such as time and temperature dependency, and the eŠect of suction in unsaturated soils. Experimental observations show that the normally consolidated line (NCL) in the void ratio-stress relation (e.g., e-ln s curve) shifts depending on the change of strain rate, temperature, suction and others (stage III). The validation of the model at stages I and II is demonstrated by simulating one-dimensional consolidation tests for normally consolidated, over consolidated and natural clays. The applicability of the model at stage III is veriˆed not only by the simulations of time-dependent behavior of clays in one-dimensional element tests but also by the soil-water coupledˆnite element analysis of oedometer tests as a boundary value problem. The extension from one-dimensional models to three-dimensional models is easily achieved by deˆning the yield function using stress invariants instead of one-dimensional stress s' and by assuming an appropriate ‰ow rule in stress space. The details of the modeling in general three-dimensional stress conditions will be described in another paper (Nakai et al., 2011).
