Modelling of engineered barrier systems (EBS) in deep geological disposals spent nuclear fuel requires sophisticated approaches that include highly nonlinear constitutive models. The Barcelona Basic Model for Expansive soils (BBMEx) is an extension expansive unsaturated the (BBM) slightly-to-moderately soils. In this extension, parameter ...

In the present study, characterisation and quantitative microanalysis were identified for six expansive soils of which one is natural soil, i.e. black cotton (BC) soil remaining prepared by mixing BC with different percentage bentonite. The samples characterised X-ray diffraction (XRD) scanning electron microscope (SEM). regular or irregular mixed layers justified SEM images. There are superstr...

Crack development in a changing environment is the controlling factor for stability and strength of expansive soils. Expansive soils exhibit large volumetric changes with their moisture conditions that may occasionally lead to reduced bearing capacity foundation failures. This study purports model crack initiation its spatial progression relation content drying period, respectively. Volumetric ...
