Porosity and water saturation percent, or their product—the water content—are important parameters for most hydrogeologic studies. Geophysical methods, especially the resistivity method, are routinely applied to studying ...

Within the GeoSIS_Lx project, a geotechnical data base is being implemented and methodologies to generate tridimensional geological and geotechnical models of the city of Lisbon are being developed. The generation of the ...

O presente trabalho constitui uma reflexão sobre abordagens de riscos no domínio das barragens de aterro e procura contribuir para a compreensão e para o desenvolvimento de metodologias e métodos de apoio à implementação ...

The complex nature of soil behaviour can only be modelled by advanced constitutive models. This type of models has the disadvantage of requiring a great number of parameters (material model constants and internal variables ...

High density polyethylene (HDPE) geomembranes are used in many geotechmical engineermg applications, remaining sometimes exposed to climatological conditions for a long time. They are expected to experience degradation due ...

A mobile projection centre extension to an existing elastoplastic-viscoplastic soil model is presented in this work. In this formulation, the projection centre evolves according to the stress path experienced by the soil, ...

A finite element method, based on *p-y” curves, is suggested for the design of laterally loaded piles. The pile is treated as an Euler-Bernoulli beam embedded in the soil, while the soil medium is replaced by a system ...

Os métodos de prospeção geofísica apenas são eficazes na deteção de um determinado alvo se ocorre um contraste da propriedade física medida entre este e o meio envolvente. Na presente comunicação aborda-se a capacidade do ...

Propõe-se um método expedito (curvas p-y) para o dimensionamento de estacas isoladas sujeitas a cargas laterais. Esta proposta tem por base uma análise prévia das principais vantagens e inconvenientes dos diferentes modelos ...
