Název v původním jazyce

Double structure hydromechanical coupling formalism and a model for unsaturated expansive clays

Popis výsledku v původním jazyce

A formalism for double structure hydromechanical coupled modelling of aggregated unsaturated soils has been developed. Independent coupled hydromechanical models are considered for each structural level, including independent measures of macromechanicaland micromechanical effective stresses. The models are linked using a coupling function to obtain the global response. The individual components have been selected to represent the behaviour of compacted expansive clays. The macrostructural mechanical model is based on the existing hypoplastic model for unsaturated soils. Hydromechanical coupling at each structural level is efficiently achieved by linking the effective stress formulation with the water retention model. An essential component of the model is representation of microstructural swelling. It is demonstrated that its calibration on wetting induced expansion measured in oedometric (mechanical) tests leads to a correct global hydraulic response, providing a supporting argument
