      A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red siltstone with interbedded sandstone strata. Dam stability is essentially controlled by the available shear strength of sedimentation ...
    • Low-strain shear modulus dependence on water content of a natural stiff clay 

      Lima, A; Romero Morales, Enrique Edgar; Pineda, Jubert Edgar; Gens Solé, Antonio (2008)
      Text en actes de congrés
      Accés obert
      This paper shows the results of an experimental programme aimed at evaluating the low-strain shear modulus of a stiff clay (Boom clay, Belgium) and its dependency on water content changes (or, alternatively, degree of ...
    • The effect of drying-wetting cycles on the seismic properties of an anisotropic claystone 

      Mitaritonna, Giuseppina; Pineda, Jubert Edgar; Arroyo Alvarez de Toledo, Marcos; Romero Morales, Enrique Edgar (2009)
      Text en actes de congrés
      Accés obert
      The evolution of bar and shear wave velocities during a drying wetting cycle on a claystone is presented. There is a clear relationship with total suction, established by means of the material water retention curve. The ...
