      Article
      Accés restringit per política de l'editorial
      This paper presents the development of a new high-pressure triaxial apparatus specifically prepared for inducing and tracking the degradation of clayey rocks. Total suction—used to induce the hydraulic degradation—is applied ...

      Article
      Accés restringit per política de l'editorial
      A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red claystone with inter-bedded sandstone strata. Claystone weathering was identified in vertical and horizontal profiles of water content ...
    • From saturated to unsaturated conditions and vice versa 

      Lloret Cabot, Marti; Wheeler, Simon J.; Pineda Jiménez, Jubert Andrés; Romero Morales, Enrique Edgar; Sheng, Daichao (2018-02)
      Article
      Accés obert
      Representing transitions between saturated and unsaturated conditions, during drying, wetting and loading paths, is a necessary step for a consistent unification between saturated and unsaturated soil mechanics. Transitions ...
