“…It can be concluded from these observations that identical increments of suction or mechanical stress produce the same change in void ratio (volume) as long as the material remains saturated. This joins the results of many authors such as: Benchouk et al, [4] Biarez et al, [7] Derfouf et al, [9] Li et al, [22] Lu et al [24] and Zerhouni. [42] .…”

“…It follows that the correlations of Biarez and Favre, 1975, established for C c and C s , remain applicable for I d and I w . (e.g., Benchouk et al, [4] Biarez et al [7] and Derfouf et al [9] )…”

“…In terms of volume change, another interesting aspect is the analogy between the effect of mechanical stress and that of suction. By comparing the results of mechanical consolidation and drying tests, some authors (e.g., Benchouk et al, [4] Biarez et al, [7] Fleureau et al, [11] Li. [21] and Li et al [22] ) found that the drying curve of saturated slurry was equivalent to an oedometric consolidation curve, provided that suction was smaller than the airentry value, that is, the soil remained quasi-saturated.…”

This article presents the results of experimental work carried out both in situ (coring; pressuremeter test) and in the laboratory (drying-wetting and oedometric tests) to describe the volumetric behavior on drying-wetting path of a swelling clayey soil of eastern Algeria. In order to perform drying-wetting tests the osmotic technique and saturated salts solutions were used. These suction-imposed methods have gained widespread acceptance as reliable methods for imposing suction on soil specimens. They allowed to sweep a wide range of suctions between 0 and 500 MPa. The ability to impose suction on soil specimens allows for drying and wetting stress paths to be applied to evaluate resulting changes in state parameters (void ratio, degree of saturation and water content). These paths were carried out on specimens with different initial states. Slurries of soil were used to characterize the reference behavior, while the undisturbed soil samples allow to describe the behavior of material under in situ conditions. In the last part of this article and to specify the behavior observed in the saturated domain, a comparison between the resulting deformations of the drying-wetting test and those resulting from the oedometric test was made.

“…Several studies investigated the hydraulic hysteresis between drying and wetting SWCC for non-expansive soils [17,[19][20][21][22][23]. Soils with appreciable clay content were observed to have a more visible hysteretic behavior than clayey silt soils.…”

“…Further categorization of the technical literature revealed that most studies related to the hysteresis of SWCC were carried out under a single drying-wetting cycle [20][21][22][23]36,37]. There are a limited number of studies that were carried out under several drying-wetting cycles for non-expansive soils [12,32,35,38].…”

The Role of Stress States on the Hysteric Behavior of Expansive Soil under Multiple Drying-Wetting Cycles

Expansive soils in the field are typically exposed to cyclic wetting and drying due to climatic fluctuations and subjected to a variety of stress conditions in nature or when used as compacted layers for the construction of hydraulic barriers or waste disposal facilities. The hysteric behavior of the soil-water characteristic curve (SWCC) is a key parameter for understanding, modeling, and interpreting the unsaturated behavior of these soils under such conditions. This study investigates the effect of stress states on the hysteresis behavior of soil-water characteristic curves (SWCCs) for compacted highly expansive clay over a range of matric suction between 0 and 1500 kPa. Two test series were performed, the first test series investigated the effect of stress states on the hysteresis of SWCCs during a single drying-wetting (DW) cycle. The second test series studied the combined effect of stress applied and multiple drying-wetting cycles on the SWCC hysteresis. For the sake of comparison, the overall SWCC hysteresis due to drying-wetting cycles was quantified using the average degree of hysteresis in terms of volumetric water content (ADHθ). Furthermore, contributors to the observed hysteresis were defined using two newly proposed measures; namely, average degree hysteresis in terms of gravimetric water content (ADHw) and in terms of volume change (ADHe*). The outcomes of this study indicate that consideration of stress states on the hysteresis of SWCC for expansive clay is of great importance. The results show a dual trend for the variation of ADHθ with applied vertical stress. Furthermore, multiple DW cycles induced a significant reduction in the hysteresis (ADHθ) under low- and high-stress states up to a certain level of DW cycles, then, no further changes in the hysteresis trend were detected. It was also found that hysteresis loops under a low-stress state were concentric in shape while hysteresis loops for specimens under a high-stress state were non-concentric, with a downward shift in hysteresis loops with the increase in DW cycles.
