Devices that simultaneously facilitate controlling suction and applying a net stress on soil specimen provide soil–water characteristic curves (SWCCs) in terms of both the water content degree saturation, volumetric deformations at various applied suctions. Such tests determine specimens based measured volume changes However, studies have shown disagreements between volume–based calculated actu...

Several attempts have been made for estimating the vital swelling index parameter conducted by expensive and time-consuming Oedometer test. However, they only focused on neuron network neglecting other advanced methods that could increased predictive capability of models. In order to overcome this limitation, current study aims elaborate an alternative model from geotechnical physical parameter...

Sewer infrastructures that are backfilled with available onsite expansive soils may be exposed to damages due seasonal ground movements. Therefore, for deep excavated trenches located in nontrafficable areas, the suitability of utilizing mixtures recycled materials as alternative backfilling lower sensitivity moisture variations was studied. Extensive environmental and geotechnical testing prog...

Excavation of the galleries for geological disposal radioactive waste can induce an excavation damaged zone (EDZ), which have consequences on long-term safety repository. In this study, intact Callovo-Oxfordian (COx) claystone taken from Meuse/Haute-Marne Underground Research Laboratory in France was artificially fractured different directions, and hydro-mechanical behaviour investigated by per...

A large number of experimental studies on sand–clay mixtures are well documented in the literature; however, preparation protocol is rarely clearly detailed or varies a lot according to authors. Variations technique obviously increases challenge comparing different test results. As consequence, sample for should be kept as constant possible ensure homogeneity and uniformity samples limit result...

It is of great interest to describe and quantify the evolution microstructure for a better understanding rock deformation processes. In this study, 2D images salt are analyzed at several stages consolidation tests cyclic compression magnitude orientation solidity, coordination, local solid volume fraction, crack volume. both tests, aggregates achieved by grain rearrangement greater than that an...

The confined compression test is the most widely used to study compressive deformation of soil in a laboratory, and height–diameter (H/D) ratio has significant effect on results. However, there been limited research H/D loess deformation. In this work, series tests were carried out remolded samples using modified oedometer explore Scanning electron microscopy (SEM) investigate variation microst...
