A Constitutive Equation of One-Dimensional Consolidation Derived from Inter-Connected Tests

Effects of Friction and Thickness on Long-Term Consolidation Behavior of Osaka Bay Clays

“…A series of interconnected type consolidation tests, in which each specimen element was individually loaded, was carried out to investigate the in‰uence of the specimen thickness. This decision is consistent with the previous studies (Imai and Tang, 1992;Tanaka, 2005), in which the inter-connected type consolidation tests were carried out using soil specimen elements with a thickness less than 20 mm.…”

“…The scale eŠect on the consolidation behavior has not yet been clariˆed. Many studies have been conducted and reported on the scale eŠect, such as Berre and Iversen (1972), Aboshi (1973), Ladd et al (1977), Jamiolkowski et al (1985), Mesri and Choi (1985), Imai and Tang (1992), Yin et al (1994), Imai et al (2003), Tanaka (2005), and Leroueil (2006). The objective of this study is to empirically clarify the scale eŠect.…”

Examination on Time-Dependent Soil Models in One-Dimensional Consolidation

“…However, if one plots the incremental change in void ratio for the two specimens during this second load increment, as shown in Fig.6, the two compression curves are almost parallel to each other. Although this result initially appears to conform to Hypothesis A behavior (as suggested in [9]), this is misleading as the initial void ratios of thin and thick specimens are different at the start of the load increment.…”

Increase in Undrained Shear Strength of Clay with Respect to Rate of Consolidation

“…Imai and Tang (1992) and Kang and Tsuchida (2000), using inter-connected consolidation test, investigated diŠerence of stress-strain curves in soil elements that have diŠerent drainage path lengths under a series of instantaneous loading. According to their obser- vations, the diŠerence was signiˆcant between soil elements close to the drainage boundary in the test.…”
