      This research presents an alternative methodology to estimate suction in triaxial tests carried out under constant water content. A preliminary determination of the retention curve is proposed using two complementary ...
    • Analysis of the collapse behaviour of a natural soil using the Barcelona Basic Model 

      Mascarenha, Marcia Mª dos Anjos; Cordao Neto, Manoel Porfirio; Murrieta, P.; Romero Morales, Enrique Edgar (CRC Press, 2009)
      Part of book or chapter of book
      Restricted access - publisher's policy
      The analysis of the hydro-mechanical and microstructural behaviour of a natural collapsible silty clay is presented in this paper. The analysis allowed concluding that a conventional model can be applied for the levels of ...
    • Análise do comportamento de solos não saturados a pequenas deformações 

      Mascarenha, Marcia Mª dos Anjos; Cordao Neto, Manoel Porfirio; Murrieta dos Santos Neto, Pedro; Romero Morales, Enrique Edgar; Alonso Pérez de Agreda, Eduardo (2008)
      Conference report
      Open Access
      Nos últimos anos tem aumentado o interesse no meio geotécnico em relação ao comportamento dos solos a pequenas deformações, sendo que a maioria das pesquisas estão relacionadas a solos saturados, não considerando a influência ...
    • Assessment of the volume change behaviour of clay aggregates by ESEM observations

    • Characterisation, mechanical and microstructural behaviour of an unsaturated silt 

      McCloskey, G..; Sánchez, M.; Romero Morales, Enrique Edgar (CRC Press, 2009)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This study investigates an unsaturated silt sampled from an embankment along the Bengawan Solo River in East Java, Indonesia. Load and soak oedometer tests were carried out on laboratory compacted samples and on undisturbed ...
    • Degradation of partially saturated argillaceous rocks: influence on the stability of geotechnical structures 

      Pineda, Jubert Edgar; De Gracia, M; Romero Morales, Enrique Edgar (CRC Press, 2009)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This paper presents the results of an experimental programme aimed at evaluating the degradation phenomena of an argillaceous rock due to the application of hydraulic cycles. The degradation of shear strength parameters ...

    • Investigation of crack desiccation in soil from a flood protection embankment 

      Atique, A.; Sánchez, M.; Romero Morales, Enrique Edgar (CRC Press, 2009)
      Part of book or chapter of book
      Restricted access - publisher's policy
      Drying causes shrinkage in soils and may yield the formation of crack. This paper reports on various experimental observations on desiccation tests performed in the laboratory under controlled conditions over samples of ...
    • Pore size distribution effects on the hydro-chemo-mechanical behaviour of bentonite 

      Musso, Guido; Romero Morales, Enrique Edgar (2009)

      Material and its preparation. Hydro – mechanical behaviour in oedometer conditions with 0.05 M , 0.10 M and 5.5 M NaCl solutions. Chemical induced swelling of samples saturated with a 5.5 M NaCl solution
    • Progressive emergence of double porosity in a silt during compaction 

      Casini, Francesca; Vaunat, Jean; Romero Morales, Enrique Edgar; Desideri, Augusto (CRC Press, 2013)
      Conference report
      Restricted access - publisher's policy
      The paper deals with an experimental investigation of water retention properties of a statically compacted unsaturated low plasticity silt. The objective is a deeper understanding of the evolution of an aggregate type ...
    • The influence of drying on the small strain shear modulus for static compacted Boom clay 

      Vaunat, Jean; Merchán, V; Romero Morales, Enrique Edgar (CRC Press, 2009)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This paper presents experimental results concerning the influence of drying and compaction on the small strain shear modulus (G0) of samples of a Boom clay reconstituted in the laboratory. For that purpose, samples of Boom ...
