PhD Thesis

• PEREIRA J.M. (2005) Study of hydromechanical couplings and non-saturation effects in geomaterials. Application to underground structures. PhD thesis, ENTPE - INSA Lyon (in french) (see abstract [+])

    Taking into account unsaturation effects in modelling the behaviour of geomaterials is a key issue in many civil engineering applications. After a synthesis of the main characteristics of unsaturated soils behaviour and of several recently proposed constitutive models, a general framework for modelling purposes is proposed. This framework constitutes a methodological tool allowing an easier extension of existing elastoplastic models to unsaturated states. This methodology is then used to extend a complex elastoplastic model (CJS). The obtained model is validated using laboratory tests.
    In addition to this rheological contribution, a computational code using the finite element method has been developed. The boundary value problem discretization is presented. Simulations of pressure-meter tests and underground cavity deconfinement with this numerical tool are proposed and analysed. They contribute to evaluate the effects of a partial saturation on the behaviour of the ground surrounding the work.
    
    Keywords: unsaturated soils, constitutive model, effective stress, elastoplasticity, hydromechanical couplings, finite elements, pressure-meter, cavity expansion.
