Large Strain Consolidation in Unsaturated Porous Media

Gareth presented a consolidation model that allows for the effects of desiccation which is prevalent in slurried mineral waste deposits in areas of high evaporation. The coupled model is based on conventional large strain consolidation of saturated porous media extended to include the effects of partial saturation using the Richards equation. The model can accommodate …more

Evaluation of the Stability of an Arch Dam Founded on Fractured Rock

Antonio outlined a case study involving three dimensional finite element analysis of a 150m high arch dam founded on fractured Cretaceous limestone. Key constraints were limited abutment resistance and unfavourable defect orientation. Details of data acquisition including in situ rock mass shear testing were presented. The finite element analysis modelled discontinuities using individual joint elements …more
