“…For this reason Hypothesis A is used in geotechnical practice as an initial approximation of the complex behavior of cohesive soils. Hypothesis B is a widely accepted assumption in creep phenomena studies (Degago et al, 2009;Watabe et al, 2012). Fig.1.…”

Soil creep deformation refers to phenomena which take place in many areas and research in this field of science is rich and constantly developing. The article presents an analysis of the literature on soil creep phenomena. In light of the complexity of the issues involved and the wide variety of perspectives taken, this attempt at systematization seeks to provide a reliable review of current theories and practical approaches concerning creep deformation. The paper deals with subjects such as definition of creep, creep genesis, basic description of soil creep dynamics deformation, estimation of creep capabilities, various fields of creep occurrence, and an introduction to creep modeling. Furthermore, based on this analysis, a new direction for research is proposed.

“…Values reported by Pineda et al (2016) (Table 2) were obtained at strain rates larger than the value imposed during IL tests which, for soft clays, typically ranges between 1·0 Â 10 À7 s À1 (Watabe et al, 2012) and 2·5 Â 10 À7 s À1 (Mesri et al, 1994a;Terzaghi et al, 1996). Although a correction factor was suggested based on the work by Watabe et al (2012), uncorrected values were intentionally reported in Pineda et al (2016), allowing the predictors to make their own estimates.…”

“…The values of R at different strain rate levels including R 0·001 were calculated using Equation 2, using e o and C c in Table 2. Table 3 indicates the calculated R, together with R based on the relationship proposed by Watabe et al (2012) in following equation…”

Isotache model for consolidation with a small incremental load

2To examine the applicability of an isotache model, two types of consolidation test were carried out: constant rate of strain (CRS) by changing the strain rate during the test, and an incremental loading (IL) test with small incremental ratios. It is found from the CRS tests that the stress shift caused by the strain rate change is nearly the same for all tested soils, but the behaviour after the change is different: some soils do not follow the isotache model. After selecting two typical soils (one follows the isotache model and the other does not), IL tests with various increment ratios and different durations at the loading stage prior to the incremental load were carried out to investigate how these parameters affect the strain-time relation. It is revealed that the strain-time relation is strongly governed by the magnitude of stress increments; in cases of small increments, most of the settlement is generated after the end of the primary consolidation. It is found that most test results can be interpreted by the isotache model. However, when the load duration at the loading stage prior to the incremental load is longer, the time-strain behaviour differs from that predicted by the isotache model.
