It can be concluded that this model can predict the hydromechanical behavior of the unsaturated overconsolidated soil under both the drained and undrained conditions.Wu, ShengshenWang, WeigangWu, BishengEuropean Journal of Environmental and Civil Engineering...
1 have been run to explore the effect on the pullout capacity of the following factors: overburden stress, soil properties, interface properties, and drainage conditions (drained or undrained). The elastic properties of the reinforcement are the same for all cases: modulus of elasticity (E) 200...
This aligns with a previous 23-year litter-bag study on aboveground litter (leaves, stem, shoot) decomposition in an undrained peatland (Latter et al., 1997). In boreal peatlands, single-exponential models generally provided a poor fit across above- and below-ground litter (a total of 39 ...
drained and undrainedoverconsolidation ratioconstitutive modelThe soil deposits for general constructions and mining are often under both saturated and unsaturated conditions at different overconsolidation ratios. Within the frameworks of the unified hardening unsaturated model, in this paper, a constitutive ...
For a given soil, the relationship is nearly unique regardless of the CSD, ACU or ICU stress path, and the critical state concepts and the second-order work criterion work well. Theoretically, it is shown that the conditions for instability under the drained and undrained stress paths are the...
During December, emissions from the drained soil (1.8±0.6 gN ha –1 h –1 ) were composed entirely of nitrous oxide, but losses from the undrained soil (2.7 ± 1.1 g N ha –1 h –1 ) were almost entirely in the form of nitrogen gas (the fraction of N 2 O in the total loss ...
Water tables in paired artificially drained and undrained soil catenas in Iowa. Soil Science Society of America Journal 57: 774-781. DOI: 10.2136/sssaj1993.03615995005700030 025x.James, H.R., and T.E. Fenton. 1993. Water tables in paired artificially drained and undrained soil catena in Iowa...
The results indicate that confining pressure obviously influences the relaxation process of warm frozen soil. Under undrained condition, with increase in confining pressure, the critical relaxation duration tends to grow as well as instantaneous relaxation. But the relaxation rate is sensitive to ...

Orientations during drained and undrained triaxial shear tests on an artificially made clayey soil were studied. The results show that the orientation pattern before shearing is nearly random, although there may be some degree of preferred orientation caused by the overburden pressure. Becoming higher ...
